A CardDAV SOGo Link looks like this

https://<url>/SOGo/dav/<username>/Contacts/personal/

It can be set up to look like this

https://<url>/dav/<username>/Contacts/personal/

If I insert the link in the browser I still bet error

Thank you for trying my extension.

Unfortunately SOGo Server is NOT compliant with the CardDAV standards published by the IETF and so can not be considered a CardDAV server despite their claim.

I do list SOGo Server as unsupported on my AddOn's page and provide a link to give more information about the issue. The only way that SOGo will be supported is if they make their system compliant with the appropriate IETF standards. I can only suggest that you contact SOGo (https://sogo.nu/) directly and ask them to make their system standards compliant.

Thank you.
