Cant login to Hass.io

I installed a fresh install of ubuntu 19.10 last night on my laptop and now I cant login to my Hass.io machine.
I can get to the login page and add my username and password, but then I get “Unable to connect to Home Assistant. Retry”

I can login using windows on the same laptop, my phone also continues to work with no problems.

Any help would be appreciated

Clear the browser cache and try again.

Sorry I should have added, I have cleared the cache and cookies in chrome, firefox and chromium but still no good

Im an idiot. I was playing with the proxy setting in Ubuntu yesterday and left it on :face_with_hand_over_mouth: whoops!
