Same behaviour as described here #5620 but in my case there are no certificate errors in the log.

When I try to open a remote container it looks like it works except for activating all the extensions defined in devcontainer.json. It happens for me and some of my students using Windows 10 when connected to eduroam Wifi. The problem only appears for some Windows 10 Laptops, not every Windows 10 Laptop is affected. We didn't notice those problems with Ubuntu Laptops.

In my Wifi at home, with the same laptop which was connected to eduroam before, after rebuilding the container it works as expected: all the extensions defined in devcontainer.json are installed.
So it maybe has something to do with eduroam (enterprise wifi?).

Any ideas what we could do? We can't see any helpful error messages in the logs.

Can you please share the remote server logs?

[Kiolali]

yes. logs are attached
logs.zip

[sandy081]

Attached logs does not contain remote server logs and they include all sessions logs. Can you please provide the log of the remote window?

• Please repro the issue again
• F1 > Open View... > Log (Remote) - provide this log

[Kiolali]

I can only test it once a week and today it works using eduroam wifi. Is it possible to see the "Remote Server" Logs from last week? Is it a file which is stored somewhere?

[sandy081]

Yes, remote server logs are stored in the disk in the server (remote) machine.
To know where the server bits are installed, please open remote settings.json file and get its location. Eg:

Now you can find all logs under following folder

${parent}/.vscode-server-insiders/data/logs

[Kiolali]

Sorry - I don't understand. What do you mean by "server bits"?
I only have a settings.json, which is located in the .vscode folder. I can't find any other settings.json

[Kiolali]

I got it now. Using the terminal i figured out the location of the logs. Unfortunately, there is only one folder with logs from today (although it's the folder/devcontainer which did not work in eduroam wifi)

[sandy081]

Please provide the remote server logs if you are able to reproduce it again.

[Kiolali]

I tried on three different days, problem didn't come back. I'll close the ticket and open it again, when it happens again.
