My installed certificate seems to be OK (see below the dotted line) but when linking to the website the browser shows a bad certificate:
This certificate has expired or is not yet valid
Issued to: sunyulstercs.org
Issued by: Let’s Encrypt Authority X3
Valid from 5/19/2019 to 8/17/2019
Any help would be greatly appreciated.
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: sunyulstercs.org
I ran this command: sudo certbot certificates
