Name does not end in a public suffix

I attempted to issue a certificate for the following gtld, but an error occurred.

gtld : xn–tckwe
error : Name does not end in a public suffix

Does Let’s Encrypt support .xn–tckwe?

This is a known bug with the Let’s Encrypt CA software. IDN domains with non-IDN TLDs (e.g. コム.com) work, but IDN TLDs ( are currently broken.

A fix is in progress, but for now you just have to wait.

Thank you very much :grin:

That issue shows that people are now getting success issuing for IDN TLDs (so it’s a great time to try again!).
