Hi Alan,

Try Adding:

options = NO_SSLv2 
options = NO_SSLv3 
options = NO_TLSv1 
options = NO_TLSv1.1

Hello:

I have not been able to get STunnel to disable these protocols.

In the STunnel.conf file I put in the line
sslVersionMin = TLSv1.2

I have disabled these in windows 2019 via reg keys

But this has not stopped scans from seeing TLSv1.0 and 1.1

Any help would be appreciated
