I have my Channels server being monitored by Uptime Kuma at it's URL of https://server-id.u.channelsdvr.net:8089/ and have recently started getting daily warnings that the domain channelsdvr.net is near expiry. WHOIS records confirm that it's due to expire on July 25th.
Just posting here to be sure the devs are tracking the impending expiry of the domain.
