So, on Friday, I turned on substream viewing for live playback on all 4 cameras. The next time I tried to login, I got the message: Could not connect: [111] Connection refused after logging in. I have already tried restarting the server, and making sure all server updates are installed (via apt). So far, neither option has had any success. I might try unplugging the cameras temporarily.
Update: according to the logs, I’m getting a segfault. I tried ‘systemctl restart bluecherrt.service’, but it segfaults immediately again.

Ubuntu 20.04.2 in an LXC environment.
I’m using Proxmox as the hypervisor, btw.
try this package:
wget http://lizard.bluecherry.net/~curt/releases/focal/bluecherry_3.1.0-rc3_amd64.deb ; sudo dpkg -i bluecherry_3.1.0-rc3_amd64.deb

Thank you, sir! That got the service to stay up, allowing me to realize: I didn’t have a substream URL configured for one of my Cameras, but I told the system to use it for live streaming. D’oh!
This worked for me too.
Hi. I got the same message, and applied the mentioned package.
After 2 days, the error reappeared,
what i’ve seen in the logs are:

so around 4AM server hanged. I’m running the dvr server on ubuntu headless
Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-84-generic x86_64)
Additional note. When motion detection is turned off, the server sun stable for days. With motion detection on, the server hangs every day between 2 and 4 AM.
It’s a bit strange behaviour.
Thanks. Can you please run this command in the evening and include /var/log/bluecherry.log. This will run the server is debug mode and hopefully provide better logging of what is happening.
sudo service bluecherry stop
sudo /usr/sbin/bc-server -l d
Ok, I’ve started the server like this.
Sidenote, i’ve still had the issue even after updated to the latest version.
2021/10/14 08:50:09 [error] 852#852: *167 FastCGI sent in stderr: “PHP message: PHP Warning: socket_connect(): unable to connect [111]: Connection refused in /usr/share/bluecherry/www/lib/bc_license_wrapper.php on line 185” while reading response header from upstream, client: 10.8.0.6, server: , request: “GET / HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php/php7.4-fpm.sock:”, host: “<:…>7001”, referrer: “https://<…>:7001/login”
Thanks. Does sudo service nginx restart fix this?
no clue. I’ve reinstalled my box to ubuntu 21.10. now i cannot install bluecherry. 
performed a clean isntall to my box, and now its working.
