Other than that, no output on failing to connect.

Environment (please complete the following information):

• OS: Arch Linux
• Java Version: 17.0.12
• Ghidra Version: 10.1.4 (Server), 11.0.3 (Client)
• Ghidra Origin: extra repository

Additional context
I am able to SSH into the server, I can see the server is listening on the correct ports, but trying to log in doesn't log anything to console.

Has anything about the configuration of the client/server/network changed since it last worked? Nothing about Ghidra itself would have changed, so figured out what changed on your end will be vital to getting it working again.

No, the server still has an uptime from before it happened so there was no restart, I didn't update any dependencies, the IP is still the same, etc.
The only thing I can think of is a local system update but that seems unlikely to have been the cause since it was maybe 5 dependencies unrelated to Ghidra or any native libraries it might use.
