Cannot logon - logon page reload with Start Over button

Dear all,

Little help requested. When accessing HA from the internet I cannot logon because after credentials are entered the page reloads and display a “start over” button. Credentials are correct for sure. Checking the browser logs I see that ‘gm2oyR_Q4unQz0eoloXxhB4CaoI.js’ raises a 404 error every time after a long pause in page load. I’m using Traefik as a reverse proxy but nothing unusual show in its logs. Funny is, if I access from my local network the issue won’t happen even when I force traffic going through the reverse proxy by configuring the local hosts file of the client computer. Browser logs follow:
