I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not able to contact the local server. I have tried several solutions suggested here in stackoverflow, tried to uninstall and reinstall PostgreSQL 9.6.2 , tried to modify the config.py, config_distro.py, and delete the files in Roaming folder,i tried standalone pgadmin4 installation, but no success.However, in my local machine i am able to access the server using psql.exe and log as as superuser (postgres user). Can you please suggest any possible solutions to starting/running pgadmin4 ? Thank you.
I found the same issue when upgrading to pgAdmin 4 (v1.6). On Windows I found that clearing out the content inside C:\Users\%USERNAME%\AppData\Roaming\pgAdmin\sessions folder fixed the issue for me. I believe it was attempting to use the sessions from the prior version and was failing. I know the question was marked as answered, but downgrading may not always be an option.
Note: AppData\Roaming\pgAdmin is a hidden folder.
Start pgAdmin 4 as administrator.
Do the following steps:
Right click pgAdmin 4 icon
Select "Run As Administrator"
I had the same issue on Windows 10, with a new installation of PostgreSQL 10.
I solved it by including the path C:\PostgreSQL\10\bin ({your path to postgresql}\bin) to system environment variables.
To access environment variables: Control Panel > System and security > System or right click on PC, then > Advance system settings > Environment variables > System variables > Path > Edit.
I've been dealing with this for awhile (frustrating). So much that I have instructions on my desktop consolidating all of these ideas. Here is my magic combination to the solution:
Delete from App Data C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
Add to Path Variables C:\Program Files\PostgreSQL\9.6\bin (I actually added it to both user and system)
Right click and start as admin.
You don't have to do this every time but when it gets out of wack try these steps.
What finally worked was downgrading to pgadminIII-v.1.22:
It seems in most of the cases Postgres trying to use information from previous sessions to find/connect the server and failing. Clearing out the previous session info helped me, it is a combination of 2 already mentioned answers above:
Navigate to Postgres session's folder
C:\Users\YourUsernameOrAdmin\AppData\Roaming\pgAdmin\sessions
Delete all the data from this folder.
Start PgAdmin in administrator mode.
Cheers!
if you are using Mac OS X here is a fix:
Open terminal and run this command
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log restart
and for other OS just restart your Postgresql server, it will solve
Then start pgAdmin4, it will start as normal

Deleting the contents of C:\Users\%USERNAME%\AppData\Roaming\pgAdmin directory worked for me!
I had same issue on windows. I had v1.6 installed as well as v2.0. Uninstalling v1.6 allowed me to login.
I had the same problem, but running it as an admin worked.
Have you recently installed a new version of pgAdmin ?
This issue (and the misleading message) is simply due to the fact that old versions of pgAdmin are unable to read the settings saved by a newer version of pgAdmin !
Make sure you're starting the right version of pgAdmin (your shortcuts are likely to point to the old version !) and/or uninstall the old version: the upgrade wizard doesn't do it for you !
Deleting contents of folder C:\Users\User_Name\AppData\Roaming\pgAdmin\sessions helped me, I was able to start and load the pgAdmin server
I had the same issue on the macosx and I renamed .pgadmin (in /users/costa) to .pgadminx and I was able to start pgAdmin4.
In Windows Just go to this path and clear it
,that works !!
C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
I was able to solve the problem by changing the pgAdmin web interface port.
I believe this problem occurred on my computer because I have several other services consuming webs ports like qBittorrent, IDEJetbrains, etc.
Right-clicking on the pgAdmin logo near the clock is possible to configure it.
I Fixed it in windows 10 just running pgAdmin 4 as Run as Administrator .
If you use older postgresql version like 9.x and its services is running,PgAdmin 4 confused which server is base database.
So stop the service older version or new one.Run PgAdmin 4 as Administrator
Its worked for me
This is often a firewall problem. The firewall log then shows dropped packets between 127.0.0.1: and 127.0.0.1:, where the latter is the port shown in the Browser to get no connection with. This means, that the connection between pgAdmin client (high_port_1) and pgAdmin server (high_port_2) is blocked. Check your firewall log and if you find dropped packets like described, adapt your firewall settings accordingly.
If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.
I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).
After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!
Keep in mind that python command will not be available from command line if you remove it from PATH.
I use the cmd prompt on Windows 10 with psql postgres postgres.
Then I launch pgAdmin4 and it works.
I had this problem with pgadmin4 v2.1 on linux fedora 27
Solved by installing a missing dependency:
python3-flask-babelex
Just click on that pgadmin 4 icon and run as administrator. Allow the access permissions. It will start locally.
I need to add this here because I've had several issues with this message. If you have recently upgraded to High Sierra you will find the latest (pgadmin 4.20) will keep appearing with the message "Application Server Could Not be Contacted". What this actually means on Macs is that python was unable to configure your environment in ~/.pgadmin
This directory stores all the things you setup and configure and even logs of what was ran on your user copy usage of pgadmin.
The way to fix this issue on High Sierra is down to sqlite3. If you look in that directory you'll see everything is stored in sqlite3 files.
When version 4.20 of pgadmin was released it was shipped with a version later than sqlite3.19 and the problem arises because High Sierra is shipped with sqlite3.19, so to fix this issue, you need to replace the old version of sqlite3 with the latest on your packager.
Now be aware, MacosX+ all use sqlite to store details for the majority of apps on your mac, so you'll need to make sure you do not just wipe the old version but you'll have to have both versions co-existing together in harmony to avoid anything major occurring on your mac.
1) download brew https://brew.sh/
2) update brew and upgrade brew to make sure it's up-to-date
3) brew install sqlite3
4) mv /usr/bin/sqlite3 /usr/bin/sqlite3.os
5) ln -s /usr/local/Cellar/sqlite/3.21.0/bin/sqlite3 /usr/bin/sqlite3
6) /usr/bin/sqlite3 -version (check version is later than 3.19)
You can now proceed to open up pgadmin as normal
Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.
However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.
downloaded pgadmin 4 v2.0 and install it no problem atm on force installation. try it. that was solution for me.
For my case in Windows 10 for postgresql 10 version, it worked by changing SERVER_MODE to False in config_distro.py placed in web folder, as per these configuration settings: https://www.pgadmin.org/docs/pgadmin4/dev/desktop_deployment.html.
There are other settings mentioned in this answer (https://superuser.com/a/1131964) regarding python but I just changed SERVER_MODE and it worked.
Kill it in Windows Task Manager and then try again. It seems that there is some sort of a problem when accessing the server from different applications.
As for me on windows 2012r2 it's start to work only after I reinstall pgAdmin 4 to folder c:\pgAdmin4. With out spaces and any special chars.
And all so I give full permission to this folder in NTFS.
It worked for me after installing python2.7 for pgAdmin 4 v2
Happens mostly when you have multiple versions of pgadmin installed or while trying to upgrade. Even I tried everything from killing the "running PID on port 5432" to "changing the server mode". In my case I uninstall postgres and re-install it again on different port(5433).
Later, I opened it through cmd(right click on cmd and select "run cmd as an Administrator").
installing an application from a command line on a mac
Hope someone can help.
I need to reinstall Final Cup Studio 2 on my mac. Since I've change to the new operating system: Lion, I'm not able to reinstall the application from the installations disks because PowerPC applications are no longer supported with Lion. One suggested solution, seems to work with many people, is to instal the program from the command line with the following argument:
$ sudo installer -package /Volumes/Final\ Cut\ Studio/Installer/FinalCutStudio.mpkg -target /
After what appear to be a "successful installation", the program is no where to be found :(.
Another solution was to add the specific PATH to were the application/s are going to reside:
/Volumes/[MainDrive]/Applications/
The problem with this is that I don't know hoy to add the additional information to the command line.
I've created a subfolder named: FINALCUTSTUDIO2 under the Applications Folder and would like to give a command to install the applicationto that particular
Rosetta, the program that lets you run PowerPC binaries on Intel processors, was taken out of OS X starting with Lion. There's no way to make it run on Lion, unfortunately, even if you got it installed somehow.
my application needs SQL Compact SP1 and SP2 installed (Entity Framework), but there is nothing on MSDN where I can determine silent install parameters for those two files (SSCERuntime-ENU-x86.msi for SP1 and SSCERuntime-ENU.exe for SP2). And on top of that, 64bit SP1 needs to be installed like this: install x86 file and then install x64 file on 64bit machine. Any thoughts appreciated.
OK, I've figured that out myself - all you need is to take these install files, run CMD and run them with wrong parameter, for example: C:\SSCERuntime-ENU-x86.msi -myAwesomeFlag. Because of course given parameter will not be found, install process displays MessageBox with a list of all possible parameters and their options. This works for both servicepacks and .NET 4 installation package.
Generally speaking .msi install parameters are normalised compared to .exe (which can be anything the developper choose). I recommend using this command with those parameters for silent install: msiexec /i SSCERuntime_x86-ENU.msi /qn /norestart
q is for quiet
n is for No UI
norestart ensure that the computer doesn't reboot right now, this is useful if you deploy software with tools like SCCM, Chocolatey, etc. Otherwise if the software needs a reboot it will reboot the computer and if a user is working on it he will not be really happy ;)
I can no longer use / at the windows xp command prompt, and it seems to have started after a botched cygwin installation, e.g. cd /windows won't work, but used to.
Can anyone think of how this might have happened?
OOPS! It doesn't normally work in XP, though I had read that it does in Vista. I simplified my problem and it was wrong. The real problem is:
I was using the cwrsync binaries (meant for cygwin use) that can be used at the command prompt in a way such as:
ssh -i /keydir/keyfile user#server
but after doing something (seems like it was installing cygwin), and even after reinstalling the cwrsync files, I can now only do:
ssh -i \keydir\keyfile user#server, i.e. I have to use the windows convention when referring to local files.
I posted this on the cwrsync forum, but it's not very active, so I was hoping someone might recognize what's going on here, I should maybe try the cygwin forum too.
Actually, since DOS 2.0, the kernel and file APIs have always supported forward slash, and many command line calls. See: http://blogs.msdn.com/larryosterman/archive/2005/06/24/432386.aspx.
I used to go to great pains to detect the OS and use a PATH_SEPARATOR type constant in PHP, when I discovered this by accident (it's use is now considered deprecated, in lieu of a simple "/").
Cheers.
You imagined it - it never worked.
If you happen to be in C:\ and type
C:\>cd /windows
it will take you to C:\WINDOWS\ but that's only because /windows is not a valid option to cd, so it tries ignoring the /.
Forward slash is a path separator in UNIX and cygwin, but Windows uses it for commandline options, eg. dir /w.
