I have the same issue with my Hass OS system stuck on 2025.6.1. When looking at the logs with ha supervisor logs -vf I see warnings like “no supervisor internet connection”.
When running ha network info I see supervisor_internet: false .
Rebooting the system did not help. ha network reload also did not change anything.
Running curl on the machine works and returns the expected data.
What can I do to fix this?
