What's the IP of the http-01 challenge?

Hi,

 

We're trying to install the free buypass SSL certificate using certbot on a server behind a firewall.

 

We whitelisted buypass.com, and I was able to register the server, but I got this error message. That question is posted a month ago. The OP says that the http-01 challenge IPs have changed

 

This question, from 11 months ago, says to whitelist

 

IPv4: 185.62.160.0/22
IPv6: 2a03:520::/29

 

should we whitelist those IPs or different ones?
