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: webwork.cavehill.uwi.edu
I ran this command:
- sudo certbot renew --force-renewal
- sudo openssl verify /etc/letsencrypt/live/webwork.cavehill.uwi.edu/chain.pem
- sudo openssl verify /etc/letsencrypt/live/webwork.cavehill.uwi.edu/fullchain.pem
- sudo openssl verify -CAfile /etc/letsencrypt/live/webwork.cavehill.uwi.edu/chain.pem /etc/letsencrypt/live/webwork.cavehill.uwi.edu/cert.pem
It produced this output:
- no renewal failures, forced renewal since certificate was not trusted, issue not resolved
- /etc/letsencrypt/live/webwork.cavehill.uwi.edu/chain.pem: OK
- CN = webwork.cavehill.uwi.edu
error 20 at 0 depth lookup: unable to get local issuer certificate
error /etc/letsencrypt/live/webwork.cavehill.uwi.edu/fullchain.pem: verification failed - C = US, O = Internet Security Research Group, CN = ISRG Root X1
