The team isolated the issue to two specific vectors:

A. TLS Deprecation Conflict: The MediaCat 201201 client executable uses an embedded version of a legacy HTTP library.

The legacy client library was defaulting to TLS 1.0/1.1 during the handshake, causing the firewall to drop the connection packets as "unsafe." If you service more than 10 Stihl units

B. Corrupted WinINET Cache: Upon further inspection, it was found that the MediaCat update process did not clear the temporary internet files used by the embedded browser component. Corrupted index.dat files caused the application to cache old authentication tokens, leading to session conflicts when trying to communicate with the updated server.
