Can't connect to Thunderbird with Hydroxide as a service

[byjove01]

I need to browse my mails frequently, so that I installed Hydroxide as a service. I created a soft link between /root/.config/hydroxide/auth.json and ~/.config/hydroxide/auth.json in order to synchronize logins. Then I followed the ReadMe and gave my authentification infos to Hydroxide, including the TOTP, before setting up in the server config correct values for ports, Connection security to "None" and removing the @protonmail.com part of the mail address. Before you ask, I obviously did put the bridge password into the e-mail password field instead of my mail provider's one, always before the TOTP code expires (how frustrating it is).

But even dozens of various attempts didn't allow me to connect that damn Thunderbird to Hydroxide. Each time, I get either the "Unable to login at server" error or the "Incoming server already exists" one, that generally happens when I try to use the "manual configuration" button to create the account and set up the password then.

I'm sick of wasting my time, so I plead for your help.
