I’ve followed the tutorials here to have my website use let’s encrypt to switch to https. today my website went down and the error i see when i visit it is “Error 526 Invalid SSL certificate”
I tried to renew let’s encrypt certificates through ssh and got the following:
root@vps1053567:~# sudo certbot --nginx -d x.net -d www.x.net Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator nginx, Installer nginx Cert is due for renewal, auto-renewing... Renewing an existing certificate Performing the following challenges: tls-sni-01 challenge for x.net tls-sni-01 challenge for www.x.net Waiting for verification... Cleaning up challenges Failed authorization procedure. www.x.net (tls-sni-01): urn:ietf:params:acme:error:tls :: The server experienced a TLS error during domain verification :: remote error: tls: handshake failure, x.net (tls-sni-01): urn:ietf:params:acme:error:tls :: The server experienced a TLS error during domain verification :: remote error: tls: handshake failure IMPORTANT NOTES: - The following errors were reported by the server: Domain: www.x.net Type: tls Detail: remote error: tls: handshake failure Domain: x.net Type: tls Detail: remote error: tls: handshake failure 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. Additionally, please check that you have an up-to-date TLS configuration that allows the server to communicate with the Certbot client.
Any ideas what could be the cause of this issue?
Thank you in advance!
