Crash - Argo tunnel issue

Hey everyone,

I’m super new to HA and currently transition to HA from Openhab. I’ve installed HA on a Raspberry 4 and already added all me devices and entities some month ago. I now would like to really start integrating HA, create some rules, etc. But unfortunately HA crashes a lot of times. And as I’m so new to the system I don’t really understand the best way for debugging… honstly said… I have no idea how to really check the logs.

The logbook (I’m not sure if its really called like this in english I’m from germany and for me it says “Logbuch”) doesnt really show me system logs or anything. I only see status changes of devices.

The problem itself looks like to come from cloudflare which I used to be able to acces HA when not being at home. I made this based on a youtube video of german guy called simon42.

Here is how it looks if HA is crashed and I try to open the app.

Maybe someone already knows were this may come from? But also some guidance on how to debug this would be helpful.

Try with a new SD card

Yes it’s logbook in English too. If you’re getting an Argo tunnel error, that’s coming from Cloudflare, so you’re not successfully getting to HA - therefore nothing in the HA logs. Assuming you’re using the cloudflared addon, you should look in the logs for that as well to see if there’s anything relevant (Settings > Addons > Cloudflared > Log).
