Hi,

I tried to apply your diff on browser.class.php, no result.

I always have

192.168.0.1 - - [18/Dec/2020:09:17:23 +0100] "PROPFIND /glpi/caldav.php/calendars/users/bob/calendar/ HTTP/1.1" 404 143 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Thunderbird/78.5.0"

Do you have another hint to find out the problem ?

Hello,

I have a similar problem with my glpi instance, which using a CAS auth.

My error is :

Applying this patch on GLPi 9.5.4 resolved same issue here. Thanks.

Edit: sorry, I commented too fast !

It resolved accessing URL from Firefox browser , but not for Thunderbird !?!
Edit2: it is resolved with Thunderbird too !

Still not from my side.
Are you using glpi with nginx ? I still have a 404 not found even from firefox or thunderbird.

Just switched from nginx to apache2 and magically, it's working.
I think about a rewrite rule not applied by nginx, or something else related to the web server.
