I have installed collabora docker image on ubuntu 16.04 and set up apache as per the instructions on the collabora site (https://nextcloud.com/collaboraonline/) You have to scroll donw to the section titled “Getting Started in 3 Steps”.
I got a letsencrypt certificate and it all looked to easy to be try… and it was. If I clicked on any doc to edit I just get a half loaded collabora UI with a spinning circle saying “connecting”. The only issue I can see is the error below from the docker instance logs.
[ docbroker_003 ] ERR Exception while invoking poll [docbroker_003] callback: No acceptable WOPI hosts found matching the target host [nextcloud.abc.co.za] in config.| ./net/Socket.hpp:382
I have no idea how to fix this. I have searched and found people with similar problems but their solutions do not work for me. For example it seems the documentation has been updated for the correct apache config. I assume this is some kind of DNS error but the site in pingable by dns name from the host.
I can also resolve the host name of the nextcloud server from within the docker image “openssl s_client -connect nextcloud.abc.co.za:443” works fine from within the container
