Build is scheduled, but worker is not starting
Dear Support,
We have a problem:
Builds job are scheduled and started, but worker is not starting again and again. The same situation if there is only one build in a queue:
2026-01-14 17:05:48.649
Warning
Worker 6a5fe24c9b4a44d683a4cb836b605f70 has not started the job - switching to failover cloud
Best regards,
Oleg Sharuda

Hi Oleg,
We are having problem with
Ubuntu1804and1604images as they don't work with newer certificate roots. Please switch your builds toUbuntu(which is 22.04) image.
