Fix SSL issues. NET::ERR_CERT_DATE_INVALID

Need a fix for let’s enscrypt SSL certificate. I host a couple of sites in a server. I use let’s enscrypt for SSL for the websites. However sometime I get the ssl error NET::ERR_CERT_DATE_INVALID. See attachment for the error in google chrome and firfox. The issues is sometimes the sites loads okay. Other times it shows this error. Have no idea what the problem is. I thought it was server time issue. I tried timedatectl set-local-rtc 1 --adjust-system-clock. But issue still persist. Looking for somebody that have experience this before and know the solution. Will require a directive to fix and prevent this from happening again. Questions, suggestions and opinions are welcomed. Generic/automatied bids will be ignored.
