Question
How to remove support for TLSv1.1 and TLSv1.2
I am completed stumped on this one. I have tried for months to figure out why SSLabs shows my domain as a B (still supporting these). I have researched and researched and cannot figure it out. There is NOTHING in my nginx folder. There is nothing in the let’s encrypt config. I have also searched Apache and can find nothing. I thought it might be that the server hadn’t been rebooted, but that just went through one and still there.
centos nginx apache let’s encrypt

Hello @doughboy
Some time ago, I’ve created a similar mini tutorial here in our community about disabling old TLS versions which you can check here:

Hope that this helps!
Hi @doughboy,
To disable your TLSv1.1 and TLSv1.2 protocols, you need to remove them from Nginx. Go to your Droplet:
Once in the Nginx folder, you’ll need to remove the protocols from the files that usually have them -
/etc/nginx/nginx.conf,/etc/nginx/sites-available/example.com.confand from time to time in the/etc/letsencrypt/options-ssl-nginx.conffile.Open them, find the
ssl_protocolsline and remove both TLSv1.1 and TLSv1.2.Another way to go about would beto grep for ssl_protocols:
Every file you get as a result, open it and see if there are ssl_protocls mentioned. Remove TLSv1.1 and TLSv1.2 from them.
Once done, restart Nginx:
