Can't access my home assistant frontend

Hi guys, I can’t acces my home assistant in my RPi 3 B +.
I updated to home assistant 7 last week and it was working nice 4 days.
It is powered on, I can access by samba and see all files correctly.
The supervisor says all ok, even my telegram bot sent me notifications so it is working.
But can’t access over IOS app or my lan desktop over xxxx.duckdns.org:8123
Error not reachable.
I checked duckdns too and it is not down.
Any help please?
Thanks in advance.

Hi guys, I found a solution!
Add here for helping others.
In my case, I found that couldn’t access from internal network, but yes, from external. (So strange because it was working long time), but.
I shared network from my 4g phone to my computer, and it worked as usual.
Then I added the internal and external addresses on configuration → general configuration,
external url: https://my_domain.duckdns.org:my_port
internal url: https://my_internal_hass_ip:my_port
Check configuration and reboot server.
Done! It works.
Just with a difference than before: now I must use the internal url for accessing from home instead of external how I was doing.
BE SURE YOU USE HTTPS IN BOTH CASES.
Hope it helps.

So I have the opposite issue. Can’t access from external and can internally. All was working fine until I upgraded today. My internal/external URLs from config are the same post upgrade.

Any suggestions please.

@daveco ave you checked your duckdns service? Are you using https?

After the upgrade the configuration.yaml required the proxy from the docker to be setup.
