These are not the one i am looking for right?
So could you please tell me which file i am looking for and where that file is located? Thanks in advance!
Yes, or just easier: SSLProtocol +TLSv1.2 +TLSv1.3.
# This TLSv1.2 only
SSLProtocol TLSv1.2
# To use TLSv1.2 and TLSv1.3 uncomment line below and comment one above. Please read note above.
#SSLProtocol +TLSv1.2 +TLSv1.3
Then TLSv1 should still be disabled right? Which isn’t the case at the moment.
I am a huge linux noob, i am afraid that i break my Nectcloud. Restoring will take a couple of hours if i mess up. Could you point me in the exact right direction @dev0 ?
Just check your Apache and OpenSSL version TLSv1.3 is now supported in Apache2 version 2.4.36 with OpenSSL 1.1.1.
This is how my ssl.conf looks like:
<IfModule mod_ssl.c>
# Pseudo Random Number Generator (PRNG):
# Configure one or more sources to seed the PRNG of the SSL library.
# The seed data should be of good random quality.
# WARNING! On some platforms /dev/random blocks if not enough entropy
# is available. This means you then cannot use the /dev/random device
# because it would lead to very long connection times (as long as
# it requires to make more entropy available). But usually those
# platforms additionally provide a /dev/urandom device which doesn't
# block. So, if available, use this one instead. Read the mod_ssl User
# Manual for more details.

This is the error i get when i restart apache service.
Job for apache2.service failed because the control proces exited with error code.
See “systemctl status apache2.service” and “journalctl - xw” for details
When i try: SSLProtocol TLSv1.2
I am able to reset the apache service. But still according to ssllabs.com i support TLS1.0 and TLS 1.1, so not working…
The cypher suite is mostly used to get rid of old, unsecure browser or systems witch may be a risk factor. Also, depending on the protocole used ( tls1.3 or other) you may want extra security
Modern : Modern clients that support TLS 1.3, with no need for backwards compatibility ( win7, older os/browser )
Intermediate : Recommended configuration for a general-purpose server
Old : Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8
