The server where I want to upload is on the same LAN.
In FM15 I choose Upload to Filemaker Server and when I choose the local server. Fill in credentials (what sometimes isn't possible) and click on next. Immediately I get the message Unable to Connect.
I also tried with the FM14 installation I still have but the same problem occurs and get the message Unable to Connect.
I've found more messages of people with this problem and tried possible solutions (ssl on, check ports etc) but with no positive effect.
