Sorry to bother you in public, but in the absence of PMs, not sure how best to reach you.

I remember some time ago getting an email from you about changing the A record for potp.it. I finally realised that I had not done so, but when I went to CloudFlare, it would not accept the AWS address and borked at the alternative IP address you gave me with DNS Validation Error (Code: 1004): Invalid proxied mode. Record cannot be proxied (Code: 9041)

What do I need to do?

Many thanks.
