" Error while trying to create admin user: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [1698] Access denied for user 'root'#'localhost' "

Manage to connect through the terminal, but not through the remote explorer

I am coming from notepad, and am learning how to work with VS Code.
I am now trying to access my online repertory on the webserver.
I followed up the guide here: https://code.visualstudio.com/docs/remote/ssh
I did manage to access my server through the terminal window.
(ssh user#domain + password).
When connecting, this shows in the log:
"Linux infong-eu27 4.4.246-icpu-061 #2 SMP Thu Nov 26 10:58:41 UTC 2020 x86_64"
This tells me that it is working on Linux.
If I type "Ls", I can see my folders and navigate among them.
So far, so good!
Second phase: Connecting through the remote explorer.
Step 1:
I configured the ssh with the same credentials I used with the terminal.
Step 2:
I am opening the remote explorer, I can see my server's name. I right click on it and select "connect".
Step 3:
I am then asking to choose the system. I am picking Linux as shown earlier when connecting through the terminal.
Step 4: I am entering the same password I used before to connect in the terminal.
Step 5: Infinite loading, or a very long one till I get 2 notifications / errors:
Could not fetch remote environment
Failed to connect to the remote extension host (error time limit..)
That being said, it also says in the bottom left corner, in the "remote window", that I am connected. This does not seems right.
Any chance someone could help?
I am frustrated because it connects in 1s using the terminal, but not in the remote explorer.
UPDATE:
I found this article on medium that paraphrases the official documentation.
https://medium.com/#sujaypillai/connect-to-your-remote-servers-from-visual-studio-code-eb5a5875e348
I managed, through Git bash, to create a ssh pair key, and managed to copy one on my server.
I then followed the instructions on how to set it up on VS Code successfully!
Now, when I try to connect, I am asked for my key pass:
But, when I do: super long loading, and the same error message.
When I looked on my server with a sftp software, I see that VS did manage to connect as files were installed in a VS folder it created:
This is reported in issue 4415 (no answer) and issue 4204
The last one includes:
This might be caused by our new automatic port forwarding feature which scans the remote OS for available ports in order to forward them locally (microsoft/vscode#112843)
This is fixed by PR 113342, for the next 1.54 Feb. 2021 release. That bug is about setting remote.autoForwardPorts to false and... still seeing VSCode auto-forward ports!
Check on your server (while VSCode attempts to connect) if:
the CPU is high
if there are any services running on public port on said server
I solved a similar issue by following the error logs from the remote ssh extension. I had to install libatomic1 on the remote server with
sudo apt-get install libatomic1

raspberry pi openvpn: ERROR: Cannot open TUN/TAP

I'm getting the above error when trying to connect to vpn given a .ovpn file. Usually this bug happens after an upgrade occurs and you haven't restarted yet. But I already did and the error still exists. I have tried reinstalling the openvpn (I'm using 2.4.7 on debian) and would not like to use this on docker.
Since getting this error when executing the command sudo openvpn file.ovpn often returns vague errors such as the one above, you can produce a more specific error when trying to import the ovpn file into NetworkManager instead.
After installing network-manager of course:
nmcli con import type openvpn vpn file.ovpn
Connect to the profile:
nmcli con up id vpn
Running this command would immediately show you a clearer error that is something along the lines of the org freedesktop networkmanager vpn plugin being unknown. Which is then solvable by installing the said plugin.
sudo apt install network-manager-openvpn
And that should do it.

winexe error: Cannot connect to svcctl pipe. NT_STATUS_ACCESS_DENIED

Am trying to execute the following winexe command, but it throws 'ERROR: Cannot connect to svcctl pipe. NT_STATUS_ACCESS_DENIED.'
winexe -U domain/username%password //windows_machine ipconfig
debug info shows,
ERROR: smb_raw_open_recv - NT_STATUS_ACCESS_DENIED
ERROR: on_ctrl_pipe_error - NT_STATUS_ACCESS_DENIED
ERROR: Cannot open control pipe - NT_STATUS_ACCESS_DENIED
When i have 'winexesvc.exe' in Windows machine, the command works.
My understanding according to http://opensourceinfo.blogspot.com/ is that winexe itself creates winexesvc service, starts it and tries to connect to control pipe. If that's the case, what setting should i have in Windows to resolve Access Denied error and get the service installed successfully? Please correct me if am wrong.
I also came across similar issue in https://sourceforge.net/p/winexe/bugs/35/ post, but am unable to understand the given resolution 'I was trying to log on via a domain user, but only local users were configured'
Note that I have already set,
1. Network Access: Sharing and security model for
local accounts" to "Classic – local users authenticate as themselves
2. LocalAccountTokenFilterPolicy to 1.
So do we need to manually place winexesvc.exe in Windows machine for winexe to work or can we fix the above Access Denied error?
Thanks in advance.

Connecting to a remote CentOS machine

I am trying to connect to a remote system which has CentOS running on it from a Windows machine. I am getting the following error:
My remote computer is on and is available on the network. I tried following the steps mentioned on this website http://www.techotopia.com/index.php/Remote_Access_to_the_CentOS_6_Desktop to enable remote access on centos as well.
Currently I can access the remote sever through commandline utility like Putty only.
I use VNC for remote GUI admin work on CentOS device's from windows its nice and easy to set up and use, below are links to CentOS 6.5 set up guide and 7
https://www.howtoforge.com/vnc-server-installation-centos-6.5
https://www.howtoforge.com/vnc-server-installation-on-centos-7
Let me know how you get on :)
As posted by PaulM, I followed the steps in the website to install VNCServer on the centos machine.
To connect from my linux machine, I wrote the following commands:
vncviewer
IPAddress:5901
Adding the port number specifically made it work
CentOs to centOs Only
No Need Any Softwares Already Centos have TigerVnc Viewer
1.Enable Remote desktop in your centos system
Goto System-->Preference-->Remote Desktop
**i.Enable allow other user to view your Desktop**
**ii.Enable allow other user to control your Desktop**
**iii.You must confirm each access to this machine allow or cancel**
**iv.if you ask any password to enable and type your password**
