We're having very frustrating intermittent error in Management Reporter:
A connection to the server could not be established. Check the server address and try again
OR
Can't connect to the Management Reporter Server. Do you want to specify a different server address?
MMR Version: 2.12.16003.25
Dynamics GP 18.4.1384
We have to wait a bit at the workstations and keep testing, it is totally random. It may take 3 minutes or 10 minutes or maybe even all day for the error to surface, but again nothing consistent. And, I've been randomly trying to get the error on a workstation that had the error at around 2pm and I haven't gotten an error.
Once it connects and we're working it may randomly return the same error when generating a report.
We've checked out the obvious:
-Mismatched version between Client & Server
-User Permissions
-Date and Time Zone of clients are with 5min of the server
-MMR Services Login is a service account with Admin rights
-MMR uses port 4712 and we have set up an MMR Inbound Rule
-The Event Viewer doesn't show MMR errors at all
-Service has been stopped and restarted
-Firewall is off
It's the hardest problem to troubleshoot because it's so random. Please let me know if anyone else has had the same problem!
Thanks in advance for any insight you can provide
