I use HA OS on a NUC, and I used to connect it remotely (either with a web browser or the mobile app). I use the DuckDNS extension, which redirects to my home router. The router is configured to redirect the HA port to the NUC.
It used to work correctly until the August update. Basically, I get a timeout.
* Host myhost.duckdns.org:8123 was resolved.
* IPv6: (none)
* IPv4: myIP (correct)
* Trying myIP:8123...
* ipv4 connect timeout after 9881ms, move on!
* Failed to connect to myhost.duckdns.org port 8123 after 10002 ms: Timeout was reached
* Closing connection
curl: (28) Failed to connect to myhost.duckdns.org port 8123 after 10002 ms: Timeout was reached
I have checked the new network menu, commented out the HTTP config with no success. I have cleared caches and force-reloaded, which worked in some random cases…
It is using the 8123 port, I have checked the port redirections on the router. And they were working correctly before the update.
Here is info about communication from work (not working) and from home (working)
