Post upgrading Terraform Enterprise version to v202310-1 or higher, plans and apply runs get in queue mode
The archivist logs shows errors related to TTL exceeding the maximum:

The task-worker logs an Unexpected HTTP response:

Cause
The error messages shown are related to a known issue in Terraform Enterprise (TFE) versions after v202310-1.The issue is specifically with the "Plan/Apply Run Timeout" setting in the TFE site admin's Settings section.
When this setting is configured to a value above 24 hours, it can cause Terraform plans to hang or become stuck, preventing them from completing successfully.
Solution
In the TFE Admin Settings: https://<insert-tfe-hostname>/app/admin/settings , under Terraform Timeout
Change the plan and apply timeout to a value equal/below 24h
