I have a SOGo server running version 2.2.10 and I am having connection/
synchronisation issues with Thunderbird and Lightning for calendar, tasks and

I have been using SOGo for some time, initially with only the web interface.
I recently decided to use the Thunderbird client. I installed Thunderbird
17.0.11 ESR and Lightning 1.9.1, along with the SOGo connector and integrator
add-ons (version 17.0.6). I followed the configuration guide, including
modifying the extensions.rdf file to include the correct address, such as
This matches the Apache config file for SOGo:
RequestHeader set "x-webobjects-server-port" "443"
RequestHeader set "x-webobjects-server-name" ""
RequestHeader set "x-webobjects-server-url" "";

Everything worked fine when tested and used on my local network. I have now
discovered when connecting from a remote location that the calendar, tasks and
contacts from Thunderbird will not connect to the server. If I connect
remotely through the web UI these functions work normally.

If I check the properties of the calendar through the web UI the CalDAV URL is
which is identical to calendar properties set in Thunderbird.

I assumed Thunderbird is connecting to the SOGo server through port 443. Is
there some firewall setting I am missing or something wrong with my config.
Any ideas are appreciated.
