Letsencrypt certs are in date but Chrome/FF wont connect
Have a bit of a problem as both FF and Chrome are squawking that the secure connections to my sites are invalid. Chrome says cert date is invalid but I ran certbox certificates and they are all in date. FF says that the site is not configured properly.
These site have been running for months on the SSL certs, I have made no changes to the server and I don't know where to look next.
Any help is appreciated.
