A client can no longer upload databases to the server, since a few days only he claims.
When selecting the server in Share/Upload to host (I have German menus/messages, sorry), immediately a message "failed to connect" appears.
tcpdump shows that it opens a connection on port 16000 on every try, they are all closed only when the client is closed (FM18 at least closes the connection after the failure).
Everyone says that the upload uses port 443, which may be true for the upload part itself once the connection is established.
As it is SSL encrypted I can't see what's going on, and even wireshark can't decode this version.
My pet peeve since years is that "modern" applications don't show errors (like "connection to xxx:16000 failed: unknown cert issuer"), but only hints that there was a problem and don't even log the errors somewhere. A few hours of development would save tons of hours for users.
Any ideas what to do? Asking Claris to implement a "dump unencrypted tcp traffic" in the client or the server is surely futile...
