CalDav-GMX Europe Server is no longer supported #265

Closed Kakadus closed 3 years ago

Kakadus commented 3 years ago

My environment

TbSync version: 2.19.1 DAV-4-TbSync version: 1.24.2 Thunderbird version: 78.11.0

[X] Yes, I have installed the latest available beta version from https://tbsync.jobisoft.de and my issue is not yet fixed, I can still reproduce it.

Expected behavior

After entering the correct credentials, you are logged in successfully.

Actual behavior

status.service-provider-setup-failed

HTTP-Error 404 URL: https://kalender-bs-ddos.gmx.net/begenda/dav/users/ (PROPFIND)

Request:

Response: ``` GMX ... ``` (standard GMX error page) ## Steps to reproduce 1. Try to add a new GMX.net (Europe) account 2. Enter username and password (actually can be filled with random values) 3. Klick 'Next' TbSync tries to access GMX's CalDav server under https://kalender-bs-ddos.gmx.net/begenda/dav/users/, which seems to be no longer supported. I suggest to switch to https://caldav.gmx.net instead.

Is auto detection working for gmx (the first entry in the list) ? For caldav and carddav?

Kakadus commented 3 years ago

No, neither for caldav nor carddav. With Caldav, the DNS-lookup is successful but still delivers the wrong adress:

SRV record @ _caldavs._tcp.gmx.de
{"prio":1,"weight":1,"host":"kalender-bs-ddos.gmx.net","port":443,"type":33,"nsclass":0,"ttl":86335}

TXT record @ _caldavs._tcp.gmx.de
{"data":"path=/begenda/dav/users/","type":16,"nsclass":0,"ttl":86336}

(And then the same 404 error is shown)

With CardDav, the DNS request fails SRV record @ _carddavs._tcp.gmx.de

Then a 404 error

URL:
https://gmx.de/.well-known/carddav (PROPFIND)

Request:
<d:propfind xmlns:d="DAV:"><d:prop><d:current-user-principal /></d:prop></d:propfind>

Oh, I'm using a german email, (ending with @gmx.de). This is the issue with the last DNS lookup concerning carddav. It succeeds when I set gmx.net as the server. Still, carddav is unavailable.

Kakadus commented 3 years ago

I just noticed that carddav works again using the same link as before. Seemingly, GMX changed their server structure. Whatsoever, it works again!

PS: Auto detection works as well 👍
