I have an extension of ssl domain name tana[.]net[.]vn ( Note: not )
Because I did not understand the technical, I made a mistake and done repeatedly so the system has blocked the domain name tana.net.vn.
"An unexpected error occurred:
There were too many requests of a given type :: Error finalizing order :: too many certificates already issued for exact set of domains: tana[.]net[.]vn,www(.)tana(.)net.vn: see https://letsencrypt.org/docs/rate-limits/
" ( Note: not )
So far I have understood the problem, I wish you company support remove domain tana.net.vn blacklist
