Just curious if there are any limitations on issuing LE certs for .co.za domains, from a US-hosted server?
We are using LE with IIS / Windows server, and no issues on issuing certificates for any other domains (.com, .net, etc). Just tried it with two .co.za domains, and got a message "The ACME server was probably unable to reach… " the challenge file. The challenge was created successfully, and the URL of the challenge file accessible via the browser. So the error message about not being able to reach the challenge file was not stating the correct reason.
Any feedback would be very much appreciated.
