Nabu Casa Login Issues

Has anyone had issues with logging into your HA instance using Nabu Casa, but only from certain locations? I can use the remote ui url from my phone which is connected through the cell network and everything works, but when I try from my computer at work it just gets stuck at the below screen:

Unable to connect to Home Assistant.
Retrying in 55 seconds…

Also in the home assistant logs i see, but only when i can’t login on certain computers with nabu casa:

(MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from localhost (127.0.0.1). Requested URL: '/auth/token'. (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/[125.0.0.0](http://125.0.0.0) Safari/537.36)

Yes, for me any device that connects to Nabu Casa takes a few minutes to initiate a connection through to a dashboard, which is unusable because it’s too slow. Is happening on 6 devices on cellular. Also happens on LAN devices if connecting to the private URL in a browser. LAN devices connecting local are no problem.
