authorizaton requests not appearing in the gui menu

[bsi-rsims]

We successfully setup one email account, however, any requests sent by other accounts doesn't display in the menu for the app.

The logfile shows that the request is sent and told to authorize it in the gui. I've tried using external and local authorization as the setting when starting the app. I've changed the config file to have different uris for each account (http://localhost, http://localhost:8080, and http://localhost:8088). We started with the precompiled windows package which worked with setting up the first account. I've tried the python version and then downloaded the code from github and tried that version as well. I have debugging turned on and the log just stays at the authorize from the menu.

Accepting new connection from 10.0.21.113:50823 to IMAP server at 10.0.50.171:1993 (unsecured) proxying outlook.office365.com:993 (SSL/TLS)
2026-02-25 14:27:12,778: Authorisation request received for ebs-mail-prod@########.com (interactive mode)
2026-02-25 14:27:12,780: Please authorise your account ebs-mail-prod@######.com from the menu

setup: windows 2019 server (running smtp, with WWW publishing service disabled to prevent it from interfering, firewall allowed for the proxy ports and the emailproxy.exe app)

Like I mentioned, the one accuont we were able to authorize works great, we just can't get a chance to authorize any others.

Any help is greatly appreciated.

Hello,
I've encountered a similar issue on Windows Server 2016 where the authorization process wouldn't launch the webpage that opens the user validation.

I think it would be very useful if the log included the URL that was being attempted to open, so that in cases where the browser doesn't open for some reason, it could be copied and pasted to another computer where the validation process can be completed.
