July 28, 20214 yr My homeassistant docker container stopped worked entirely a few days ago and I can't figure out why. The container needs to contact `cloud.nabucasa.com` to register a cloud connection for their subscription service. Although, for some odd reason, the DNS resolution fails for that specific website in this specific docker container (strange). I've tried reinstalled the docker container twice, downgraded homeassistant version, and even tried a non officially maintained docker repo by the linuxserver guys. Nothing helps Output from NginxProxyMananger (this container works): 10.0.0.3:8888/dockerterminal/NginxProxyManager/ /tmp # ping cloud.nabucasa.com PING cloud.nabucasa.com (3.210.155.223): 56 data bytes --- cloud.nabucasa.com ping statistics --- 26 packets transmitted, 0 packets received, 100% packet loss /tmp # cat /etc/resolv.conf nameserver 8.8.8.8 /tmp # ping youtube.com PING youtube.com (172.217.13.142): 56 data bytes 64 bytes from 172.217.13.142: seq=0 ttl=117 time=23.993 ms 64 bytes from 172.217.13.142: seq=1 ttl=117 time=20.992 ms 64 bytes from 172.217.13.142: seq=2 ttl=117 time=19.273 ms --- youtube.com ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 19.273/21.419/23.993 ms /tmp # Output from homeassistant (this container fails): 10.0.0.3:8888/dockerterminal/homeassistant/ root@NAS:/# ping cloud.nabucasa.com ping: cloud.nabucasa.com: Try again root@NAS:/# cat /etc/resolv.conf nameserver 8.8.8.8 root@NAS:/# ping youtube.com PING youtube.com (172.217.13.142) 56(84) bytes of data. 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=1 ttl=118 time=22.7 ms 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=2 ttl=118 time=23.9 ms 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=3 ttl=118 time=19.3 ms 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=4 ttl=118 time=19.1 ms 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=5 ttl=118 time=14.6 ms 64 bytes from yul02s05-in-f14.1e100.net (172.217.13.142): icmp_seq=6 ttl=118 time=20.1 ms --- youtube.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5007ms rtt min/avg/max/mdev = 14.607/19.955/23.889/2.966 ms root@NAS:/# As you can see, both have internet access, both are using 8.8.8.8 dns, both can resolve youtube.com but only one can resolve cloud.nabucasa.com. The unraid host has no problem resolving cloud.nabucasa.com, its ONLY some of my dockers which fail, I'm stumped. I've tried setting homeassistant up with host network mode (as recommended), also tried giving it it's own dedicated IP and tried it in bridge mode. All modes result in the same behavior. Please offer any guidance, thank you!
July 29, 20214 yr Are you sure homeassistant use "/etc/resolve.conf for DNS setting" ? FYR, I run HA in VM. Edited July 29, 20214 yr by Vr2Io
