Good evening,
I attempt to renew my certificat since june 2021 without success.
NET::ERR_CERT_DATE_INVALID
Subject: vps12001.serveur-vps.net
Issuer: R3
Expires on: 1 juil. 2021
I ran this command:certbot renew --dry-run
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Processing /etc/letsencrypt/renewal/vps12001.serveur-vps.net.conf
Cert is due for renewal, auto-renewing...

Attempting to renew cert (vps12001.serveur-vps.net) from /etc/letsencrypt/renewal/vps12001.serveur-vps.net.conf produced an unexpected error: Failed authorization procedure. vps12001.serveur-vps.net (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://vps12001.serveur-vps.net/.well-known/acme-challenge/KJpmbwRZqT0-q8-QrMwypIu8HAjJrxC4Zh94wniJiOc: Timeout during connect (likely firewall problem). Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/vps12001.serveur-vps.net/fullchain.pem (failure)
** DRY RUN: simulating 'certbot renew' close to cert expiry
** (The test certificates below have not been saved.)
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/vps12001.serveur-vps.net/fullchain.pem (failure)
** DRY RUN: simulating 'certbot renew' close to cert expiry
Due to the result I deactivated firewall and IPTABLE but the result is same.
So I ran this command: apachectl -S

-------------------------------------
But I don't know if my problem is due to numbers of ssl domaines or a problem configuration.
Could you help me to identify my renewal problem?
Thank's you in advance.

I made an edit-mess of things.
in there.
