Error DNS Connect for many integration after blackout

Hi everyone. It’s several days, after a blackout that lasted a long time, I have been having problems with some integrations. They don’t update and they all give DNS connection errors.
I attach screenshots.
I have not encountered any other connection problems at home or any other errors relating to DNS.
I have HA Core 2024.11.3
Thanks to everyone

Ive been having similar issues on my HA green as well. Really puzzling me. No idea how to resolve it other than reboot it every once in a while
