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.

I ran this command:
Mostly we are having no trouble with certbot issued SSL Certs on several domains.
However we have two reports that users experienced browser error ‘NET: ERR_CERT_AUTHORITY_INVALID’.
Most ssl checkers come back clean but when we went to https://www.sslchecker.com and entered girlsinscience.ca it doesn’t recognize the chain of authority since it says the root cert is missing.
I see there is a Chain of Trust documentation page but it’s too technical to tell me why I am getting this error and what if anything can be done about it. My guess is that this checker makes assumptions that Let’s Encrypt has deliberately decided not to implement. And that perhaps that occasionally is true for other implementations like browsers. Or maybe something was temporarily inavailable when the chain of trust was being checked.
Do I need to worry or do anything?
