The problem

After upgrading to 2025.6.1 from 5.3 I noticed two errors in the logs and HA behaving oddly, random automations triggered as an example.

Failed to to call /core/info -

The number of occurrences has been increasing, I could not restart HA, nor can i access supervisor logs. A reboot of the server (proxmox running HAOS) restored for a short time and then the problems started again.

I cannot access backups which seem to have failed as well.

What version of Home Assistant Core has the issue?

2025.6.1

What was the last working version of Home Assistant Core?

2025.5.3

What type of installation are you running?

Example YAML snippet

Anything in the logs that might be useful for us?

Various timeout errors in core logs, no errors reported in Supervisor logs although I suspect its because Supervisor is not functioning.
