HAOS 16.2rc1 Breaks External Connections

[Happy-Cadaver]

Describe the issue you are experiencing

Upon upgrading to 16.2rc1 HA seems to lose the ability to connect to external servers. First time it even borked the connection to Nabu Casa, second time Nabu Casa is connected. Rolling back to 16.1 fixes the issue. I've cycled through this twice, rolling back for now.

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

16.2rc1

Did the problem occur after upgrading the Operating System?

Yes

Steps to reproduce the issue
