HTTPS Errors - integrations can't connect to services

Sometimes after I restart I get tons of https errors. Phone from outside home network works perfectly but it looks like I have so many errors on the launch like the server can’t connect to the cloud services.
Have a look at the screenshots.

I happens sometimes, after I reboot 15 minutes later it doesn’t happen and everything normal, it is just after some random starts.

Home assistant OS Installed on Intel NUC Proxmox VM.
OS with around 10 months of life.

If I restart the core it solves, but if I just restart “server” in home assistant it doesn’t work. looks like some sort of DNS resolving issue.
