Open AIO 4. Observe Talk container logs ### Expected behavior The Janus MCU server should be able to connect to the 8188 port. ### Actual behavior Repeated: `main.go:228: Could not initialize janus MCU (dial tcp 127.0.0.1:8188: connect: connection refused) will retry in 16s`, possibly being the cause of experienced issues on Nextcloud Talk. ### Host OS Rocky Linux 9 running Linux Kernel version 5.14.0. #### Nextcloud AIO version 2.0.3 (latest as of 2022-10-03). #### Current channel `latest` #### Other valuable info AIO is behind a NGINX reverse proxy and the domain is proxied via Cloudflare. Shouldn't conflict but no services on the host are using port `8188` regardless. SELinux is disabled and `3478/tcp` and `3478/udp` are open on the firewall. See the following logs from the Talk container: ``` + sed -i 's|#turn_rest_api_key.*|turn_rest_api_key = "84d2dd0bc699c82e874ce70cab606d4abf1ff3f86a7c9886"|' /etc/janus/janus.jcfg + sed -i 's|#full_trickle.*|full_trickle = true|g' /etc/janus/janus.jcfg + sed -i 's|#stun_server.*|stun_server = "127.0.0.1"|g' /etc/janus/janus.jcfg + sed -i 's|#stun_port.*|stun_port = 3478|g' /etc/janus/janus.jcfg + sed -i 's|#turn_port.*|turn_port = 3478|g' /etc/janus/janus.jcfg + sed -i 's|#turn_server.*|turn_server = "127.0.0.1"|g' /etc/janus/janus.jcfg + sed -i 's|#turn_type .*|turn_type = "udp"|g' /etc/janus/janus.jcfg + sed -i 's|#ice_ignore_list .*|ice_ignore_list = "udp"|g' /etc/janus/janus.jcfg + sed -i 's|#interface.*|interface = "lo"|g' /etc/janus/janus.transport.websockets.jcfg + sed -i 's|#ws_interface.*|ws_interface = "lo"|g' /etc/janus/janus.transport.websockets.jcfg + set +x Janus commit: not-a-git-repo Compiled on: Wed May 5 14:28:53 UTC 2021 Running Janus as a daemon Adding 1 external loggers Logger plugins folder: /usr/lib/x86_64-linux-gnu/janus/loggers Loading logger plugin 'libjanus_jsonlog.so'...

That’s what I quickly found, you want to check your version. Other than that, without more information, there’s no way to help.
