Cannot save new entries when phone is connected to home wifi

When I’m connected to my home Wi-Fi in addition to having my normal carrier mobile data connection I get a timeout fail error when I try to save a new entry. I believe it’s port 45464 or something close to that. When I switch Wi-Fi off I can then save. Connection is WPA/wpa2/wpa3-personal. If I leave Wi-Fi on but turn off mobile data I still get the same error.
I would imagine that it’s nothing that’s fixable but I am curious as to what’s causing this time out.

@Bkuhl welcome!

Are you able to log into the web vault from your home wifi?
