Last summer I used Let's encrypt as well as Plesk. I have encountered this problem three times since then.
"Could not issue a Let's Encrypt SSL/TLS certificate for DOMAIN" error.
Since IPv6 can't be used under my contract, troubleshooting in the above error sentence couldn't be used.
The solution I found is as follows.
Delete error website certificate. Invalid use of SSL/TLS of website, erase additional directive. Once I update the website settings. And delete the .well-known directory. Then restore the setting again. Then install the certificate with Let's Encrypt module.
I asked my close friend this symptom. It was said that this was not a Let's Encrypt but a problem on Plesk side (or a problem with Let's Encrypt plugin in Plesk).
When I first encountered this problem, I didn't know the solution and broke the whole server. This type of problem is very scary.
Is there a way to prevent this authentication problem?
