[BUG] Cannot connect to WebUI after recent update.

Is there an existing issue for this?

Current Behavior

I used duplicati for years now on Unraid, installed from the "apps store" and everything has been working well. The webui password was asked sometimes and it has been logging in just fine.

After some update I went to check the WebUI and I cannot login anymore. I tried all the password I have saved for Duplicati. I do not remember exactly which one it was because they are all on a password manager and I do not check the webui often but it was one of the ones I have saved.

I tried to set in the container the DUPLICATI__WEBSERVICE_PASSWORD=, both empty and with the password that should be set. When I get to the login page (clearly using a new UI that I never seen before) I tried every password but pressing the login button does nothing. No notice that the password is wrong and nothing in the log.

I do not know what else to try to either figure out the password or to disable it since the container is accessible only on my lan and I do not need a password.

Expected Behavior

No response
