We have web application that triggers FME Workspace on FME Flow server. Sometimes (rare case) we receive an error in the application “Failed to access module”.

Error in log files point to problem with FME saying:

2024-09-11 02:53:36.7457|Warn||||Error occurred in FMERequestor Method RequestFMEJob: System.InvalidOperationException: Failed to fetch transformation: Status: Unauthorized, Url:

http://XXXXX/fmerest/v3/transformations/jobs/id/546567

I have no idea why it is not accessible, because in 99% cases it works fine.
