Could not load dashboard website with loopback check - after 3 tries

[OrezBodajoy]

After boot I can only do curl localhost 2 times before it hangs and I get the following error on my cloudron instance:
Could not load dashboard website with loopback check

Before that, on the instance, curl localhost and curl --insecure -v https://localhost work fine but after that it just hangs (when on the same hsot).

I have updated up to the latest stable version of cloudron available now but I still have this issue. I was on 3 or 4 versions before, something like 9.0.3 (or 13 I don't remember exactly the version number).
il about 10 days ago (let's say 2 weeks?)

With netstat -ntlp | grep 80 and netstat -ntlp | grep 443 I can see that it's still listening to both ports without issue.

tcp     0    0    0.0.0.0:443    0.0.0.0:*    0    LISTEN
tcp     0    0    0.0.0.0:80    0.0.0.0:*    0    LISTEN
tcp6    ...

$ cloudron-support --troubleshoot
...
[OK] dashboard cert is valid
[FAIL] Could not load dashboard website with loopback check

Please let me know if this is expected behaviour or not.

Thanks!

Hello @orezbodajoy
Can you please inspect the /home/yellowtent/platformdata/logs/box.log logfile for errors?

This too might be related to the ubuntu kernel issue. Can you check the output of uname -nar ?

Hello @orezbodajoy
The dashboard issue is related to the latest ubuntu kernel having a regression. If you are running 110 which has a bug . See https://forum.cloudron.io/topic/15265/unusable-application/39

If you'd like to try, you could apply this patch manually https://git.cloudron.io/platform/box/-/commit/bffc97ab2fedb06100bc507abd0f8b42d343ea6e and then systemctl restart cloudron-firewall.

This should solve the issue.
