Port forwarding / firewall seems to be the logical conclusion. Is the firewall active on the server itself or only on the router? Port forwarding is something that is set up on the router so someone may have fiddled with that. If you have no experience with that, grab someone in the client's area that does and let them review the router settings.
If the firewall on the server itself is active it needs to have ports 5003 and 16000/16001 open.
Another issue could be that the internet connection at the remote location or at your location is too "laggy". The latency may prevent the connection from happening.
Thanks for all your help. We've gone part way for resolving this but aren't there yet.
It seems that what caused the initial problem was the usual Jave/FM issues. However the latest version of FM server won't run on our Mac server running 10.6. And for some reason we can't upgrade the Mac Server to 10.7. So the Mac engineers tried to install the old version of FM server to go back to where we were with only partial success. We can now access the FM files via open remote but still can't access the FM server control panel so can't upload/download the database.
The latest suggestion is a new Mac Mini set up as a Mac server.
Any other suggestions or experiences?
What could be the issue is that the 2 Tomcat instances is not running. They are needed in order to run admin console and WPE.
Take a look at my long post, where I have tried to make an extensive description on how to do.
My problems was with FMS11, but I am pretty sure that the same will apply to FMS12.
Look particular on 12)
I know that FMI server team has verified the problem and they were able to solve the issue by using my description. So I think they are trying to make an updater or easy to do solution for all.
