dashy not a single status check (not even on github.com) working

[marcelser]

I installed the newest lxc container with dashy on proxmox and it says it updated to 3.1.1 and the example dashboard shows just fine. But when I try to setup a status check on any entry (even the github.com example tile) I always get "connection timedout" with a grey dot. The LXC is based on debian12 I could see.

I already logged via SSH and did some ping, nslookup, curl and wget commands and everything worked perfectly. So it's not a connectivity issue. I also checked journalctl of dashy but there's no errors at all.

Can anybody help me with this problem?
