Exactly, and I guess that is the core problem.
And the question is: “Is it possible to configure collabora (loolwsd) that it is also binds to the IPV6 address?”
I also gave it try using collabora installation with the script mentioned here:
But the problem remains the same. Port 9980 is only listening on IPV4 not IPV6.
Any idea to get it working with IPV4 and / or IPV6?
Thanks, Brakelmann.
