Cannot find homeUrl: CalDav

[albsch]

I'm trying to connect another CalDav calendar, but something is not working with the discovery process. I get the following error:

{"level":"error","message":"Cannot connect to Dav server: {\"stack\":\"Error: cannot find homeUrl\\n    at /usr/app/api/node_modules/tsdav/dist/tsdav.cjs.js:1164:15\\n    at Generator.next (<anonymous>)\\n    at fulfilled (/usr/app/api/node_modules/tsdav/dist/tsdav.cjs.js:45:58)\\n    at runMicrotasks (<anonymous>)\\n    at processTicksAndRejections (node:internal/process/task_queues:96:5)\",\"message\":\"cannot find homeUrl\"}","tags":["REST","CALDAV"],"timestamp":"2022-09-22 08:43:54"}

I'm using something like the following URL:

https://mail.example.com/CalDAV

With Thunderbird, the discovery process works and it discovers the correct endpoint after providing login credentials:

https://mail.example.com/CalDAV/~username/Calendar/My%20Calendar/

What could be the issue here?

What provider is it please?

Could you try to add URL as https://mail.example.com without /CALDAV?

Might be fixed in 0.15.5 version

Still happening. It should be a CommuniGate Pro provider, I don't have access to it.
