HA Companion App stopped working

Hello to all.

Today, suddenly, the Home Assistant app on the iPhone doesn’t load anything and my Google Mini no longer recognizes the various home automation devices.

The DuckDNS log says:
Retrieving subdomain and token from the environment variables
log will be output to docker log

Also in the Caddy log I have an error:
err_trace “:” reverseproxy.statusError (reverseproxy.go: 783) "

What may have happened?
Can you please help me?

Thank you.

The Home Assistant LOG is full of errors:

i don’t know how work duckdns, but it seems your ip isn’t reachable from the net
is your public ip static ?it 's your internet provider dependant
if not, u have to update your ip to your dns server with a dynamic dns service.

check your public ip and check your configuration.

Hi!
I have a dynamic IP from my ISP and my FritzBox is configured to use DynDNS with DuckDNS (I used the guide on DuckDNS site).
If I check on whatsmyip I have the same IP as the one from DuckDNS.
The LOG from DuckDNS container seems to be OK.
I’m using Caddy as reverse proxy: now the LOG of the Caddy container doesn’t have any error but I still have the same errors on HA and the HA Companion App doesn’t work…
