Root Cause #1: Verbs not allowed
Resolution: In the web.config set:
verbs AllowUnlisted = true

Root Cause #2:
Event Viewer logs have below error -
[Quartz] Couldn't rollback ADO.NET connection. Transaction not connected, or was disconnected System.InvalidOperationException: Transaction not connected, or was disconnected
at void Quartz.Impl.AdoJobStore.ConnectionAndTransactionHolder.CheckNotZombied()
Error updating job state: System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while reading from the store provider's data reader. See the inner exception for details. ---> System.Data.SqlClient.SqlException: The transaction log for database 'UiPath' is full due to 'AVAILABILITY_REPLICA'.
This is mostly possible in a HA setup, but also check Event Viewer logs for normal setup as well.
