If you try to access the main communick website or the mastodon/xmpp services, you will probably receive a message about insecure connections.
This is caused due to the expired SSL certificate. Previously I was doing this task in a semi-automated method - I still had to manually trigger the process that renewed the certificates for all the machines.
I am working now on fully automating this process so we don’t have to go through this again. I will update this thread with more details.
