Connection to Remote Engines Keeps Failing

Hi People

I have a bit of a weird scenario that has stumped our IT team and our FME consultants.

Our setup is that we have FME Flow Hosted as the controller which passes the jobs to an on-premise FME Flow server.  Whenever the on-premise server is restarted (e.g. Windows patching) Flow Hosted loses the connection.

While that is to be expected, the connection doesn’t come back on its own when the on-premise engines are back on-line, nor can it be restarted (it hangs on initialising).  The only way to reconnect the Hosted service to the Remote Engines is to complete drop the Remote Engine configuration and recreate it.

Has anyone else come across this or, more hopefully, fixed it?

Thanks
