We have a firewall that has started flagging x1.c.lencr.org as a compromised website. I see Let's Encrypt owns the domain, but not sure what is going on with our firewall? I assume the traffic to this domain is legit?? Anyone else having any similar issues? Host: x1.c.lencr.org Path: / Categories: Compromised Websites

We are aware that this domain has been flagged in some systems as compromised and are working to remediate that error. Let's Encrypt owns the domain and hosts the Root X1 CRL on that domain. You can read about lencr.org here You can read a little about why we have a CRL here

What firewall and where does your firewall gets its block lists from? Any specific block list triggering the LE domain?

Possible false possitive: VirusTotal

We experienced the same thing and I opened a case with WatchGuard to find out if it's a false positive or no. They said it is indeed, so the domain should now be available again. [image] _JoshLimited: It is a Watchguard firewall. I am not sure where they get their block lists. They work with Forcepoint.

It is a Watchguard firewall. I am not sure where they get their block lists.
