I try to use a service that needs an API connection, and everything works but the provider tells me our framework is 4.7.2 and we can't work with 1.3 and please change your protocol version from 1.3 to 1.2. How can I do this?

I asked it chat GPT and it return "Apache’s SSL configuration is usually located at /etc/apache2/sites-available/default-ssl.conf or /etc/httpd/conf.d/ssl.conf. Find the SSLProtocol directive and modify it to allow only TLS 1.2: SSLProtocol TLSv1.2 You can also verify that the server is using the correct TLS version by checking the SSL/TLS configuration with a tool like SSL Labs' SSL Test, which will show the supported TLS versions for your domain. "

I do it, restart my server, and check on this website but it still shows "This server supports TLS 1.3."

    forget about chatgpt output. It has absolutely no understanding of things, and just creatively reassembles things it's seen before, or invents nonsense without marking it as invention. This is no exception, as you notice it even contains advertisement for a service, which is ostensibly where they stole the text from without giving anything back to the people that actually put in work.

    So, let's start slowly. "Our framework is 4.7.2" What framework? .NET? PHP? Windows NT? "we can't work with 1.3" what does that have to do with any framework? that's a property of the http server. So, you need to investigate why that is the case and fix that. Commented Jan 24 at 18:53

    Generally, saying "you need to downgrade to TLS 1.2" is kind of a red flag; this is what you learn to trick software into doing if you are an attacker trying to downgrade transport security to enforce usage of a known-to-be-broken cryptographic algorithm. And, come on, it's 2025, and TLS 1.3 has been around since 2018, this is a problem that should have been solved 7 years ago. Commented Jan 24 at 18:55

    Not quite as bad as asking to install Flashplayer, but along a similar vein. They need to fix their tooling. Commented Jan 24 at 18:57
  • So: maybe explain in more depth what the larger-picture problem that you need to solve is, before explaining how your (probably wrong) solution attempt failed! "State the Problem Before Describing the Solution"! Commented Jan 24 at 18:58
