Disabling TLS 1.0 and TLS 1.1

The most recent version of Certbot did disable TLS 1.0 and 1.1 in the Apache configuration.

If you can’t upgrade Certbot, I guess you could steal its configuration file. Then there shouldn’t be problems with future upgrades.

# This file contains important security parameters. If you modify this file
# manually, Certbot will be unable to automatically provide future security
# updates. Instead, Certbot will print and log an error message with a path to
# the up-to-date file that you will need to refer to when manually updating
# this file.
