Greetings, i had two wordpress sites hosted on different VPSes and recently i decided to migrate them both in order to host them in a single droplet. I configured Apache2 for multisite use as well as all the other bells and whistles. The first site migrated more easily and successfully than i imagined so i decided to configure it fully so i know what i would do with the next one. So the the thing i left for last is the installation of the SSL certificates. I use Let’s Encrypt some years now and never came across into any issue. I change the DNS settings of my domains to point the VPS’s IP and waited until they refreshed. Then i configures certbot and initiate the command
certbot --apache -d myfirstdomain.com
Usually this works and everything is setup but this time i got this error:
Failed authorization procedure. myfirstdomain.com (tls-sni-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Incorrect validation certificate for tls-sni-01 challenge. Requested 48aafb807ddb7b1f21c7c2fc4f1d9e83.fd2292837145a9884d49c01f03298219.acme.invalid from [2400:6180:100:d0::1a07:e001]:443.

Received 2 certificate(s), first certificate had names "myfirstdomain.com" To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.
After some digging i couldn’t find something so i moved on with the second migration which went excellent. So i thought that the same thing will happen when i will try certbot for the second domain but it didn’t. Everything went smoothly and the website is up and running with https redirection and everything.
I am stuck. Any suggestions? Thanks in advance
