Home Assistant not remembering connections

Home Assistant is no longer remembering my browsers at all. It will even ask for a password directly after successfully logging in and pressing reload. It’s the same in both firefox, chrome and whatever broswser I am using on my mobile.

From what I can see in firebug, no cookies are created.

I was using version 0.43.2 and upgraded to 0.44.1 with no improvement.
At the moment I have my machine IPs set under trusted_networks to avoid this at home, but that doesn’t help me when on 4G.

Anyone else with this problem?

Noone else have this error, or suggestions on where to start checking for errors?
