Hello everyone, I also have a problem to renew the certificate with a new one! The error I have is "ERR_SSL_PROTOCOL_ERROR" Removing DST Root CA X3 and throwing a new ISRT Root X1 did not give any results. But I also want to emphasize that all computers are in the DOMAIN! Thanks!!!
Hi @vadhol welcome to the LE community forum 
Please add more detail on your specific problem.
What FQDN(s) are you having that trouble with?
Which clients are having trouble (O/S+version and browser+version)?
