One of my sites with a *.su domain is no longer working, because of an expired SSL certificate. When checking the certificate status on the SSL/TLS page, I see this error:
Pending Deployment (Error)
The requested domain uses a blacklisted TLD
.su reported as potential risk: blacklist_tld
I’ve tried toggling between the Minimum TLS Version settings, but that had no effect.
I wouldn’t expect this to make any difference personally - scroll to the bottom of the edge certificates page, disable Universal SSL and then turn it back on.
