Question / Help Streamed to YouTube a few times, now nothing

[BeachBum1085]

One camera OBS setup and streamed with no issues. Started streaming Sunday morning, no error messages, 4Mbit upload, 20% CPU but now nothing.
OBS log: https://obsproject.com/logs/m3hyPGDpOC4dNJEg
Was on v.22, upgraded to v.23, streamed OK a couple of times.
After failure, uninstalled v.23, installed v.22
Nothing.
YouTube dashboard says no data received, yet Win10 Task Manager shows a 4Mbit stream from OBS.
No indication of a stream key error.

There have always been the errors (lib files not found, etc), not sure why. Just did a plain install.

Found the answer by accident. YouTube silently changed the stream key a couple of weeks ago. The problem is that the old key turns into a black hole -- no error messages, just no streaming. Now the Sunday morning checklist is to verify the key using the live stream dashboard window.
