IP flagged for potential security violations

I tried to log in to a WPMUDEV blog post to leave feedback but I get this message:
Your IP (173.245.48.169) has been flagged for potential security violations. Find out more...

When I click Find out more.... it takes me to JetPack page. I did an IP lookup and that IP is Cloudflare IP. I use cloudflare for some of my websites. That is not my computer IP.

The blog post I tried to login to was about the Hub. Any suggestions how to log in without getting this error?
