Can't login as admin in webui public hostname


I created a public hostname for my Printers webui, It seems to be working fine since It will show me the webui page but, when I login as admin it does nothing. Like When I login there is no response.
Does anyone know what I did wrong?


having the sameissue for calibre, portainer vs-code stack. Where you able to trouble shoot it or find the root cause? I had my tunnel working on a docker-compose for those application for nearly a year fine but recently having a lot of issue accessing remotely.

Not Yet, I hope someone in the community would be able to help us.
