Zyxel firewall categorizing Let's Encrypt CRL as malware

I work at Let's Encrypt, a widely used Certificate Authority - including by some Zyxel websites like support.zyxel.eu.

We've received reports that our CRL (Certificate Revocation List) URL r10.c.lencr.org arise being categorized as malware by Zyxel firewalls. I am not familiar with Zyxel products, but I do see it shows as malware on the URL checker on https://threatintelligence.zyxel.com/checker

This is a false positive. Our other URLs like r11.c.lencr.org and e5.c.lencr.org are not flagged as malware. If there's a better place to report this, please let me know.
