Required Troubleshooting Steps

• [X] I have followed these troubleshooting steps
• [X] I have tried both values of the remote.SSH.useLocalServer setting

Connect Locally

It connects successfully

->

exactly the same.

Expected Behavior

I expect this to work.

Steps To Reproduce

When connecting to remote linux machine, some strange things are happening. This part is not open source, so it is also hard to debug.

VS Code goes in cycles and reopens and retries to remote connect.

I also read here https://github.com/microsoft/vscode/issues/129483#issuecomment-903696828 a question whether this Windows is under domain, yes, this Windows is under domain and is configured by company IT department. It is also a virtual machine.

Anything else?

No response

[roblourens]

Something is messing with the network connection, probably from the corporate configuration, and I don't know that I'll be able to get to the bottom of it. Can you check for other error messages though?

• F1 > Set Log Level > Trace
• Repro the issue and check the dev tools console for errors (Help > Toggle Developer Tools)

[tinodj]

@roblourens thank you for engaging. I will do everything I can to get to the bottom of this.

• I have tried trace but it add nothing :( I will try tomorrow once more.

• I did developer tools and errors there, were the same as my last block of errors in the original message above. But will try tomorrow this part once again.

[tinodj]

Hmmm, I might find the issue. Starting this from command prompt:

"C:\Windows\System32\OpenSSH\ssh.exe" -T -D 20864 -F "C:\Users\user\.ssh\config" "hostname" bash

doesn't guarantee this port will be opened. For example now, I run this, and port opened was 20948 instead of 20864. So after running this port should be obtained somehow. I tried -D 0, doesn't work for me.

Do you have any suggestions/workaround, now when we know where the problem is?

Thank you!

Here is the log anyway:

Oh, I am sorry for not commenting earlier, we solved this around 6 weeks ago. The problem was Palo Alto Terminal Services or Terminal Server (TS) Palo Alto, as explained here:
