We are using LetsEncrypt SSL certificates for our webservers.
Currently our LetsEncrypt SSL certificates are valid till 31/05/2020.
We were informed by our server support team that since the servers we are using is running on Debian OS “Stretch” (9.6) we will have to be upgraded to latest Debian OS before Jun 2020 otherwise LetsEncrypt will not work after June 2020.
Can you please confirm that this is true. ?
Do we really need to upgrade to Debian 10 in order to continue use LetsEncrypt or will LE continue to work as now in Debian 9.6 ?
