Error handling request from 172.30.33.5

I’m running HA on Yellow Core=2025.3.4, Supervisor=2025.03.4, Operating System=15.1, Frontend=20250306.0
Since yesterday I am getting errors that key components won’t load

I have tried installing a back up that predates the error and even a clean install but nothing seems to work making me think that there is something outside HA blocking the calls, but I can’t work it out. Anu ideas? TIA
