**Action is required to prevent your Let’s Encrypt certificate renewals from breaking.**
Your Let’s Encrypt client used ACME TLS-SNI-01 domain validation to issue a certificate in the past 60 days.
TLS-SNI-01 validation is reaching end-of-life and will stop working on **February 13th, 2019.**
You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire.
If you need help updating your ACME client, please open a new topic in the Help category of the Let’s Encrypt community forum:
Attempting to renew cert (www.websec-room.com-0001) from /etc/letsencrypt/renewal/www.websec-room.com-0001.conf produced an unexpected error: Unable to find a virtual host listening on port 80 which is currently needed for Certbot to prove to the CA that you control your domain. Please add a virtual host for port 80.. Skipping.
All renewal attempts failed. The following certs could not be renewed: /etc/letsencrypt/live/www.websec-room.com-0001/fullchain.pem (failure)
