I have several domain names configured on the same IP with nginx. I have two of those domain names setup for SSL with certbot. When I attempt to renew the cert I get:
Incorrect validation certificate for tls-sni-01 challenge. Requested 8940996ca4b653594290588191f1b597.c65034c76b9204d38bb9020de5e0ffd0.acme.invalid from 188.8.131.52:443. Received 2 certificate(s), first certificate had names "admin.dockyard.com"
I have opened an issue on GH with a detail dump of the log and nginx server configs: https://github.com/certbot/certbot/issues/5340
I haven’t yet received an answer on GH to solve the issue, I’m hoping for better luck here!
