Solved (kinda..) : Caldavzap not working anymore....or does it ?

[phloks]

Hi,

I'm using caldavzap to be able to view my calendars.
There's one strange thing, though....
When I go to my calendars using Firefox (latest) at home, all works well.
However, at the office, using the same version of Firefox, when I go to my calendars, I get a page saying 'Loading resources (1 of 1)' , and it stays there..

In the webconsole I see this :

Code Select Expand

Info: loadConfig main_rc.min.js:1:25768
XML-parsefout: onjuist gevormd
Locatie:
Regelnummer 1, kolom 118:
Error: [netFindResource: 'PROPFIND https://[email protected]/davical/caldav.php/hans/']: code: '503' status: 'error' webdav_protocol.min.js:2:4066
Error: [netFindResource]: 'Unable to load resources' webdav_protocol.min.js:2:1699
XML-parsefout: niet-overeenkomende tag. Verwacht: </meta>.
Locatie: https://www.hanslammerts.nl/webmail/plugins/caldavzap/caldavzap_0.13.2/roundcube.html
Regelnummer 26, kolom 3: roundcube.html:26:3


It's in Dutch, but translates more or less like this :

Code Select Expand

Info: loadConfig main_rc.min.js:1:25768
XML-parse-error: Not well-formed Location:
Linenumber 1, column 118:
Error: [netFindResource: 'PROPFIND https://[email protected]/davical/caldav.php/hans/']: code: '503' status: 'error' webdav_protocol.min.js:2:4066
Error: [netFindResource]: 'Unable to load resources' webdav_protocol.min.js:2:1699
XML-parse-error: not matching tag. Expected: </meta>.

I looked in the firewall logging, but nothing appears to be blocked when going to the calendars page.

Any suggestions what could be the issue here, please ?

503 is a server side error so I'd recommend looking at the error log on the server to find more information.

Well, that's just it....
There seems to be no relevant logging to this problem.

When I look into the apache acces-log, I only see 200's and an occasional 207, but no 503.
Nothing is written to apache's error-log.

There's nothing in /opt/roundcube/logs/*.log either....

Replying to my own question:

It turns out that our company firewall actively blocks WebDAV.....
Since WebDAV is considered dangerous (highest classification for potential risk) this will not be allowed....

Bummert...
