Home Assistant : 401 unautorized

Hello,
I’m posting this because I’m completely blocked.
I tried to configure HA to access it away from home, using duckdns.
I now cannot do anything…
Trying to access https://MyIP.local:8123 -> 404: not found
Trying to access https://MyIP.local:8123/api/ -> 401: Unauthorized

Does anyone knows what to do?

ssh possible?
make sure HA is running

what did you recently change? undo it!!

Sorry i try to do my best.
I installed last version of HA on a raspberry pi 3 b+

I’m trying but I just can’t undo anything as I can’t access anything…

can you ssh?

is this new install?

If you understand french, I followed this topic

I configure the duckdsn like this
image

And modified the configuration.yaml adding this

http:
base_url: votre_domain.duckdns.org:8123
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

And I opened a port of my internet box

Yes from this week end!

Sorry I’m quite novice. What do you call ssh?

secure shell
connection using terminal/command line

have you check the http://MyIP.local:8123 connection? https not working but maybe http still working

maybe easier to start from new install
