Hi list, I noticed a strange behavior of CalDavZap : CalDavZap is configured with cross-domain enabled. If the certificate of the Caldav server (i.e. DAViCal) is not trusted, CalDavZap fails to connect and raises a 404 error in the console : OPTIONS https://davical.mydomain.example/caldav.php/ [0ms] "Info: [globalNetworkCheckSettings: 'https://davical.mydomain.example/caldav.php/'] crossDomain set to: 'true'" "Error: [netCheckAndCreateConfiguration: 'https://davical.mydomain.example/caldav.php/'] code: '404'" Though I didn't try, the same behavior probably exists in CardDavZap. I think that announcing "404" doesn't really help about the actual issue which is not a non-existency but a certificate problem. What not consider modifying this error message? Regards, Julien
