I’m having an odd issue that started mid day today and it’s beyond my abilities. Sometime between noon and 6pm, remote access stopped working via DDNS.
Nothing changed. No restart. No update to Home assistant. No update to DDNS. No update to NGINX. Public IP address hasn’t changed in a month. From what I can tell, nothing changed in my router. Everything has been working great for 12 months. Cert doesn’t require an update until december 9th.
Nothing in the DDNS hassio addon logs.
Nothing in the NGINX logs.
I have no clue where to look or what could be causing the issues.
Running ubuntu 18.04 desktop on a NUC.
Unifi gateway pro is the router.
Port forwarding 443 to 443 on the ip of HA for nginx, not really sure if that’s needed but I’ve always done it. Networking has never been my strong suit.
EDIT: I am getting one error in nginx
2019/09/10 21:55:38 [error] 16#16: *285 connect() failed (111: Connection refused) while connecting to upstream, client: xxxxxx, server: xxxx.duckdns.org, request: “GET /api/hassio_ingress/xxxxxxxxxxxxxxxx/ HTTP/1.1”, upstream: “http://172.30.32.1:8123/api/hassio_ingress/xxxxxxxx/”, host: “xxxx.duckdns.org”
Using the dev tools in chrome, I see this error multiple times:
resulted in a network error response: the promise was rejected
Edit again: It appears to work intermittently.
