Since upgrading to FM Cloud 17, we've had this happen 3X now in the matter of 2 weeks. This is a production server handling several retail customers.
When this happens, we have to reboot the instance and then everything is back. This is something that happened occasionally when were were on 1.15. Didn't happen much at all on 1.16.
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /fmi/webd/paygo_interface_2ndTracks.
Reason: Error reading from remote server
Any ideas on what causes this?
