Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I am using no-ip (ddns.net) and successfully renewed 3 months ago. I did some research and noticed a few people had issues not being configured for IPv6. I wasn’t, but have addressed that (no affect). The renewal file under the letsencrypt folder has manual renewal specified. I have ensured that the file in .well-known is accessible via a browser.
In reviewing logs I noticed that there is no entry from nginx in the access or error logs for an access attempt after running certbot. So it appears that the challenge is not getting to nginx, although the IP address specified is correct; so it does seem to be resolving from no-ip.
Any suggestions on where to look next or what to try?
I ran this command:
sudo certbot certonly --manual --preferred-challenge http
It produced this output:
Failed authorization procedure. xxxx.ddns.net (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://xxxx.ddns.net/.well-known/acme-challenge/rBTSDEg-JbBMGS_q4mIEECdBeA3O_aYjDS26-QGjcjE [xxx.yyy.zzz.www]: 500
