I am experiencing hit-or-miss connectivity through wireguard when connected to a specific, unsecured, public WiFi from iOS devices. Meaning, I first connect to the public WiFi at which point, wireless works fine, websites load, etc. but when I subsequently initiate a wireguard connection, most of the time, the traffic flows stops due to a connectivity issue. If I fiddle with toggling the WG connection off then on several times, it eventually works.
Through searching, some suggestions about lowering the MTU value to improve stability are mentioned. I tried lowering the MTU size on the interface to 1440 and then again to 1280 but neither made a difference. Wondering if more experienced people here have some suggestions.
Here is the log from the iOS client when I attempt to connect:

An update - if I first connect WG while the iPhone is on 5G, and then connect to the WiFi without stopping WG first, it seems to work as expected. Tested and confirmed several times. Will continue monitoring.
- Ondemand activation fails
- Connecting to the WiFi first and manually selecting a profile fails
- Only true with this specific WiFi, ondemand activation works everywhere else
