Socket error on both Mac clients

I’m using a Macbook pro (2017 model with an i5) running MacOS Ventura 13.2 and both client apps fail.

When I install either the Seafile client 8.0.10 or the Seadrive client 2.0.26, then put in the info for my server, a window pops up showing ‘Network Error: Socket operation timed out’

Is there some kernel extension that isn’t being installed or something? This server is working with other devices, including a windows client, a mac m1 client, and several phones, so I’m not sure what the problem is.
