I’ve seen a similar situation for CNAME. The user switched browsers and was able to get it to work.

Which browser (version) and OS (version) are you using?


Thanks, this is bug in settings of my browser (I don’t find, where exactly), it not Cloudflare bug.


  • Chrome Version 64.0.3282.186 (Official Build) (64-bit),


  • the newly established Firefox 59.0 64-bit portable.

I get success:


  • Firefox 59.0 (64-bit) (even in Safe mode), that I usually use,

I get bug above.


Unable to reproduce here, but I have filed an issue for our dev team to review. Thanks for the report and glad you have it working now.
