ICS calendar URL not working

[HaraldKi]

Not sure whether this should be working at all. I have an ICS calendar URL which needs no password to retrieve. I nevertheless specify a password but get the message "invalid server response, check URL" (my translation from German).

The URL does not end in ".ics", if that matters.

Should this work or is it just not implemented?

Same here, "invalid server answer, check URL". But my URL does end in ".ics" so it probably doesn't matter.

Is this maybe a duplicate of #258 ?
