Hi @Padrespio ,
You are most likely hitting Google’s limit of 5 root requests / minute.
There’s some related talk in this thread too.
First thought is to try to stagger starting up your workstations? Start a session, wait 15 sec, starts next session, wait 15 sec, etc.
Once all workstation sessions are started they should all work fine. It’s just the initial root request that’s throttled.
