Additional update Disablling OCSP Stapling in about:config -> security.ssl.enable_ocsp_stapling = false allows website to load to verify the Certificate is valid in Firefox showing it is a Firefox issue.
OCSP is a security feature and if the website supports OCSP Stapling then Firefox always checks whether the OCSP response that is stapled on the server is valid unlike other browsers that aren't that strict and are more forgiving when there is an issue. A server needs to make sure that the OCSP response is valid.
