Endless InsecureRequestWarning: Unverified HTTPS request is being made to host errors

I am getting endless log errors like these (url redacted in error)

/usr/local/lib/python3.12/site-packages/urllib3/connectionpool.py:1064: InsecureRequestWarning: Unverified HTTPS request is being made to host 'xxxxx.duckdns.org'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings warnings.warn(

I have looked around for solutions but thye all seem to be related to setting python error behaviour in docker, but I use HASS OS so I cant do that

Also this is strange behaviour as I dont actually run https on HA, its behind an nginx proxy. Some addons do run their own ssl, like Grocy, and 2/3rds of the errors are related to that addon saying the same thing (next task to address that)

But tens of thousands of these errors seem to come from core?

Any ideas?

If I understand the message correctly, it is HA that is trying to do unsecure requests.
Do you recognize xxxxx.duckdns.org?

Yes, its the url for my HA - it points at the NGINX proxy (HA core doesn’t run ssl, its offloaded to Nginx)
