As of the 1st of july (updated to v2.12.4) the docker container is doing a insanely amount of dns requests to the following domains:

To Reproduce

Expected behavior
Normal behavior dont flood DNS

Operating System

From my googling, this should only happen on startup or when creating a dns cert for a dns plugin that isn't installed at startup. For it to keep going afterwards is troubling.

How did you check this is happening exactly?

I too am currently facing this issue on the latest turenas scale.

I am also experiencing the certbot dependency errors shown resulting in a 'Bad Gateway' error when attempting to login.

@Autowaffle, may want to rotate your Cloudflare API Token from your last screenshot

Could be. When i try to login onto the webinterface it doesnt accept my credentials. Nothing happens... I reverted back to the previous version and everything is back to normal. No DNS floods, and i can login.

Everything i configered in the proxymanager seems to work though

@crluehmann WOW I'm bad at this, I even looked thanks.

Also, as this restarts and attempts to reinstall Cloudflare, it is calling out on each retry. My DNS is also 'flooded'

Yep, 28k requests here too in a few days
