Based on what was said in the other threads; have you tried deleting the dbcache folders on the client?
I do not know where these folders would be located. Would you know?
There should be a lot of good info in those other threads about this.
On your client machine:
Deleted cache folder and restarted system twice.
Confirmed ports on server. 5003 and 16000 open to inbound and outbound.
I did try uninstalling and reinstalled FMPA yesterday.
Clients are connected via Ethernet, no wireless except iOS devices.
I can connect to three different remote solutions via wan and do not experience any issues with latency. All of these remote solutions are hosted on different servers each running FMS 14.
