mailbox.org account with special characters in password

[LukasKnuth]

I have a mailbox.org account that I'm trying to add in DAVx5.

Versions

• DAVx5: 4.3.8-ose (installed from F-Droid)
• Android 13 (LineageOS 20) on Rhode

Steps to Reproduce

1. Press "Add Account"
2. Select "Login with email address" and enter both email/password
3. Press "Login"
4. After a second the Dialog shows "Configuration detection - Couldn't find CalDAV or CardDav service - Username (email address) / password wrong?"
5. Clicking "Show Details" and then "View Logs" shows the following: HTTP 401 Authorization Required

Details

• The email/password is not incorrect, logging into the mailbox.org interface works as expected
• This account does not have 2FA activated, although logging into my 2FA account also works as expected
• I have previously setup a DAVx5 account with the same email/password combination on a different device. This worked and the synchronization continues to work
• Choosing "Login with URL and user name" with the base url https://dav.mailbox.org does NOT change anything

Special Characters

I have tried the to log into a different mailbox.org account (one without special characters in its password) and this works as expected.

The password contains the following special characters: #@?{}[]()$,

Hello,

DId you try curl -vX PROPFIND -u username:password https://dav.mailbox.org and/or other CalDAV clients? Do they work with/without special characters?

[rfc2822]

I just had a try and DAVx5 + mailbox worked without problem with a password containing all the #@?{}[]()$, characters.

Curious. I didn't get it to work, so I changed the password to one without any special characters. Worked immediately.

Since it's no longer used and was auto generated in the first place, here is the password that caused issues: 11#G@lkN?NJ]2{,k2$co)jSy(,bo)e}u

No problem with that password.

Had a similar problem with a password with special characters. The log said it got a HTTP 401 Authorization Required. I then went on and used an application specific login, these come with passwords without special characters. That worked like a charm. Also it might be me not being able to type a password after checking it 10 times I thought I might comment that I encountered a similar issue 🤷
