Hi @timh​ !

Thank you for your post and I'm sorry to hear you are encountering problems with your server!

This error is sometimes seen after setting up a distributed deployment of FME, as different pages in the web interface use different ports to communicate with the FME Server core. 

For example, the Jobs, Projects, and Resources webpages use port 7071, but the Schedules webpage uses port 7073. So, if port 7071 was open between the web application server host and the core host but 7073 was closed, you would see the Jobs webpage working properly, but the Schedules webpage would show an error. 

Please see this FME Server documentation page for a full list of the required ports and ensure that all the ports required are available and not being used by other software.

Thank you, Kate. The problem is no longer there. It seems to have resolved itself. The documentation page link you provided is dead.

Is there a location in FME Server where I can see which ports are being used and by what FME Server webpages?

Happy to hear the issue has resolved itself Tim! Apologies on the article link - please see the updated link here- https://docs.safe.com/fme/html/FME-Flow/ReferenceManual/FME-Flow-Ports.htm If you expand the first section, you will see all the ports that are used by the various sections of FME Flow. Hope this helps!
