I use a self-hosted forum as a wiki knowledge base. I usually edit the topic several times a month (I’m the only one in the community who edits).
At first, the site was running in standard configuration and everything was fine. This message did not appear for no reason.
Then I connected the site to an external proxy Nginx, so that the traffic became HTTPS protected. And from that moment at least 1 time per day I see this message that the draft is being edited in another window. There are no other windows, nor are there any users editing the topic.
It seems to me that connection to HTTPS proxy caused these messages. Unfortunately, I can’t show all external Nginx settings, because this is forbidden by internal rules.
Maybe this information will help admins or developers to look away from Discourse and look towards the network settings of the environment.
