Please fill out the fields below so we can help you better.

My domain is: kendallsecurity.ddns.net

I ran this command: ./certbot-auto renew --dry run

It produced this output:

Attempting to renew cert from /etc/letsencrypt/renewal/kendallsecurity.ddns.net.conf produced an unexpected error: Failed authorization procedure. kendallsecurity.ddns.net (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://kendallsecurity.ddns.net/.well-known/acme-challenge/EKLvQ7gEQiAq8Xcc4Efru1GZ_7egdbdwk6N2k5JodZE: "

Do you had redirections from port 80 to port 443?
If yes, try to start web server only on port 443 and try renewal.
This was my workaround yesterday, “cerbot renew” not worked but “cerbot renew --dry-run” yes.
I restarted the web server with only the server instances on port 443 and it worked.

Hope this help

Yes, 443 and 80 are open…

Thanks…

Looks like ./certbot-auto renew --dry-run worked. I must have needed the “-” between dry and run.

Thanks!
