I have instance on Google Cloud Platform and I'm trying to connect it to the pgAdmin 4.
So here is my postgresql.conf
So I've tried the following:
I've wrote the instance ip as well as the username and password.
And I get the following error:
I've added my IP Address on cloud instance, but this didn't help as well.
Is there something else what I can try?
Posting this as a community wiki as this is based on the comments shared by #AdrianKlaver:
Given that you get a timeout expired error, which generally means a firewall blocked the connection, this is likely to be an issue on the port 5432 not being open to external access, so if you change that this might work.
NOTE: Just remember that you once you do this you will have opened the database to public access as determined by the IP's you allow in. Make sure your pg_hba.conf and role security are sufficient to deal with this. You can find more information on how to set this up by following both of this documenation links for Client Auth and to Create Roles

I cannot connect to my Google Cloud SQL database from my Macbook Pro using MySQL Workbench.
I have read the help file here:
https://cloud.google.com/sql/docs/mysql/admin-tools
I have added an authorized IP address for my IP per
https://cloud.google.com/sql/docs/mysql/configure-ip#add
I created a user for the database with it set to allow to connect from any host. I get the error "Can't connect to MySQL server on 'XX.XXX.XX.XXX' (60)
I have also attempted to telnet and get a consistent error that I am unable to connect to the remote host
As far as I know, I've followed all the steps but it really seems I'm getting blocked even before the server. I am trying to connect from home and I don't believe my home firewall is blocking things. I am wondering if there's something I need to open up on the GCE firewall but I have successfully connected to this database from other outside tools (e.g., Zapier).
Your best action right now would be to create a proxy with public IP address.
https://cloud.google.com/sql/docs/mysql/connect-external-app
This link will walk you through that process. If this doesn’t solve your issue, then taking your question to ServerFault (Stackoverflow sister site) might give you a better idea of how to fix your issue.
I followed the aws tutorial found here.
Everything went smoothly up until connecting to the postgresql instance via pgadmin.
I entered the appropriate user/pw info and copy/pasted the address of the db appropriately.
The port is indeed 5432 on my aws dashboard.
I am receiving the following error message:
Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Operation timed out Is the server running on host "my_database_name.some_stuff.us-west-2.rds.amazonaws.com" (52.10.228.18) and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.
For PostgreSQL servers starting with version 8.0, this is controlled using the "listen_addresses" parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use '*' to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter to 'true'.
You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error message, it's still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community.
Step 1
You are getting the same dialog I was seeing above. Crap!
Step 2
Go to your RDS instances
Step 3
Go to your security groups
Step 4
If your account was like mine you see this text:
Your account does not support the EC2-Classic Platform in this region.
DB Security Groups are only needed when the EC2-Classic Platform is supported.
Instead, use VPC Security Groups to control access to your DB Instances.
Go to the EC2 Console to view and manage your VPC Security Groups.
For more information, see AWS Documentation on Supported Platforms and Using RDS in VPC.
Step 5 Go back and check your RDS security group name (RDS->instances right click your instance). You will see something like Security GroupsList of VPC Security Groups associated with this DB Instance.
You will see something like:
default (sg-********) ( active )
Step 6 In your VPC security groups find your sg-******** that matches your database. Right click that. Edit inbound/outbound rules to add postgresql.
Try to connect again.
This solved my problem.
If this does not solve your problem I am very sorry, but I hope this documentation brings me some debugging karma.
go to AWS services in security group click on the security group id . from the "actions" button click on "edit inbound roles" and then change the "source" to "my ip"
The past similar questions have been related to mysql.
But this question is about using Google Cloud SQL, project name and access control, 1. set root password; then, 2. enter network IP.
From mysql workbench, "connect" command results in "access denied for user "root" nnn.nnn.nn.nnn (using password:YES).
Please help. I must be doing something wrong!
Your help much appreciated!!!
please double check that you enabled root password and that password is correct or try to change password.
If you get that error it means that your client (Mysql Workbech) can reach the SQL instance so networking and firewall rules are OK and even Cloud SQL access control is correctly set-up to receive request from your remote client IP otherwise you would receive a 'Lost connection at Mysql server' error.
Check e.g via whatismyipaddress.com that your client IP is not changing (Dynamic IP) and it is exactly the one you authorized in Cloud SQL access control.
Sincerely,
Paolo
I have just created a Google Cloud SQL instance. When I was looking on the access control of my instance, I found that if I want to access my database, I should authorize my IP address to get the right to access the database, but the problem is that my application will be deployed anywhere where the clients need, and even if I know where they will run the application and also I authorized their IP address, it (the IP) will be changed at least one time every 24 hours because it is not static IP, and then I have to re-authorize the IP again and again!
Is there any way to make the instance accessible from any IP?
Thanks
You can whitelist any subnet. You just need to enter it using CIDR notation: http://en.wikipedia.org/wiki/Cidr
In particular, you can whitelist 0.0.0.0/0 which includes all possible IP Address.
Please note that this is not recommended for security reasons. You want your access to be as restricted as possible.
This is an older post, but I noticed it on the sidebar so I figured I would add my 2c.
If you're able to use Cloud SQL Second Gen (currently in Beta) there is a new feature which allows access to the database without having to whitelist any firewalls: https://cloud.google.com/sql/docs/sql-proxy
Today, I was looking for a way to set-up an MS-SQL server for development purpose and found the similiar problem (how to allow my laptop to access).
This guide, helps.
In short, you need to allow firewall to enable EXTERNAL access to your VM instance at port 1433.
I've recently purchased a cloud server which has public IP and I am using it to host an xmpp server.
My first task was to ensure my users connected using my subdomain - as an example m.chat.com.
In my configuration I have the following:
%% Hostname
{hosts, ["m.chat.com"]}.
I then created an admin user with that domain.
In parrellel I have created the following DNS record with my host provider, hostgator for my subdomain m.chat.com
Name TTL Class Type Record
m.chat.com 14400 IN A [IP of the server]
One thing that puzzled me was my ability to access the ejabberd web admin console. This was achieved via: [IP of the server]:5280/admin however I could not access it via m.chat.com:5280/admin
That aside, inside the web console, under "Virtual Hosts" I could see the host "m.chat.com". I created a user "user#m.chat.com" and tried to connect via Adium.
Inside Adium, simply typing in user#m.chat.com with the password did not work. Instead I had to also specify the "Connect server" which in this case was the [IP of the server].
It has connected fine and I have registered other users to check everything is working and it is.
Then I thought I'd go back to the ejabberd configuration and start messing around. I changed the hostname to the following:
%% Hostname
{hosts, ["m.chat.com", "facebook.com"]}.
I registered a user with that domain and restarted ejabberd. Upon checking the web console, to my surprise, I could see the Virtual host "facebook.com". I tested this user in Adium with the [IP of the server] defined in the "Connect server" section and it connected fine. I asked other people with their own internet connections to use this account on their PCs and they were able to connect too.
Story over - my question to everyone is how is this possible? Am I missing something? Is there no domain authentication. After searching online, it seems you can even use fake domains.
If I am to operate my own service in the future (iOS chat app) I do not want anyone using my domain names with their own public servers.
Can someone shine some light.
Thanks!
Edit: A second question - Preferably I do not want to have to define the "Connect Server" upon using a client. I would like the client to recognise the #m.chat.com domain and establish a connection to the Servers IP automatically. Have I configured my DNS record correctly? For anyone else using Hostgator, is there an additional task I must do?
Edit: I can now access the web console via m.chat.com:5280/admin and I no longer have to specify the Connect server when using a client. I didnt do anything, I think it was a case of Hostgater updating the DNS or something, they say it usually takes 4 hours. However I am still slightly puzzled as to why I can create accounts with the facebook.com domain. I understand that because I can not access the DNS admin for this domain I can not create any records but that does not prevent me from using the domain and just specifying a Connect server.
Your initial problems (unable to access the server by using m.chat.com) were almost certainly DNS issues, and it seems you have isolated that down to the time taken to update the record.
Your second question - about the fact that you can name virtual hosts without restriction, is simple but interesting. What makes you think there should be any kind of restriction? It would be like you dictating that I can't save "m.chat.com" in a file on my disk, or that I can't send "m.chat.com" in a message across the internet.
This is why DNS exists and is structured the way it is. Although I can tell my server that it hosts facebook.com, nobody will connect to it because the DNS record for facebook.com does not point at my server (users generally don't set the "connect host" manually). Which begs the question... why would I want to tell my server it hosts facebook.com, and if I did, why should Facebook care?
An additional, but relevant, identity layer on top of DNS are certificates - which clients should validate for the virtual host name in spite of any "connect host" set. Since it's not possible to have a certificate for facebook.com, clients should generally pop up warnings or fail to connect at all. If they don't, they're probably not validating the certificate correctly.
