Hello. I keep getting a 521 error on my site: Pixelbly dot com. I follow the instructions here. I contacted my hosting provider Dreamhost and they said from their end every is fine, the CF ips are not blocked since “ we are partners” . At this point I don’t know what to do. If I pause CF, the site work fine. Any ideas?
Take a look at this #CommunityTip on Error 521, I guess this one covers more possibilities:
Railgun was the issued. Turned off and goodbye 521.
