Overnight when my machine sleeps, I cannot resume a session. However, I can resume it from the Terminal, and I can fork the session, and that will resume in the Extensions UI.

Start a session (maybe a long one).
Disconnect your computer from network overnihht
Try to restart.
What is the expected behavior?
This was working fine - I had a huge session, 250K tokens, and it had been working for two weeks in this mode.

We're reverting our extension, I'll give an update tomorrow morning.
Thanks for the bug report.
What behavior do you see when you try to resume the thread in the extension? Do you receive an error? Does it hang?
And yes, please try reverting to see if that fixes it. That information will help inform whether this is a possible regression.
Basically the submit button is greyed out, and nothing happens. The old session doesn't reappear, and it doesn't produce any output.
forking the session allows me to restart it (history is visible etc, responds to new prompts).
Also I can Terminal resume the session, and that works too. It's clearly something in the Extension itself.
FWIW, my coworker, also on a Mac started experiencing the same thing as I did. We're very far apart though, on our own personal network connections (we do joint dev on Coder managed Docker instances, but I dont think thats the issue). We are on a single corp account for the moment.
Still experiencing it.
Can concur, and I think this is possibly the same issue as #18993
