Conversations with GPT-3 to fix the Spine
The following is a conversation with an AI assistant. The assistant is helpful, creative, clever, and very friendly.
Human: Hello, who are you?
AI: I am an AI created by OpenAI. How can I help you today?
Human: Can you help me debug an SSL configuration error?
AI: Sure. What's wrong?
Human: When I open the website, it shows 'ERR_SSL_PROTOCOL_ERROR'
AI: The server's TLS configuration does not support the protocol you are trying to use.
Human: How do I fix that?
AI: Check your server's configuration. Make sure that TLSv1.0 or TLSv1.1 is supported.
Human: How do I check that?
AI: For Ubuntu systems, this can be done by running the command: openssl s_client -connect .
AI: Make sure to replace with your server's IP address.
Human: Okay, this is what it returned:

AI: I think that the issue is caused by the server being behind an HTTP proxy, not an HTTPS proxy.
Human: Can you elaborate? I'm using nginx
AI: There are two ways to solve this problem. You can either disable the proxy and connect directly, or setup TLS termination on your host and let your host deal with it. The second option is preferred because it makes future maintenance easier. I can write a tutorial explaining how to do that if you want.
Human: Awesome! Go ahead
AI: Just for clarification, we are currently logged in to your server, yes?
Human: Yes
AI: Okay, the first step is to use your distribution's package manager to install stunnel. For Ubuntu and Debian systems, this can be done by running the command: sudo apt-get install stunnel . For CentOS and RedHat systems, this can be done by running the command: sudo yum install stunnel . Please replace apt-get with yum if you are using one of these.
Human: Great, what do we do with stunnel?
AI: Stunnel is a program that can be used to encapsulate TCP connections inside of SSL connections. This is useful because we can connect to the server through an HTTP proxy, and send traffic through stunnel using SSL. This is known as TLS termination. Stunnel listens on port 443, so this means that our proxy must connect to stunnel, and not directly to the server. Then, we will configure nginx to connect to stunnel instead of directly to the server.
AI: The next step is to create a configuration file for stunnel. Since you're not behind a firewall and your hostname is, it's probably easiest to use the configuration provided by Copy the text in the green box below, and save it as /etc/stunnel/stunnel.conf on your server. Then run sudo service stunnel4 restart .
AI: Now, we need to configure nginx to connect to stunnel. Create a new file called /etc/nginx/conf.d/ssl-upstream.conf and put the text in the green box below into that file. Then run sudo service nginx restart .
AI: First, generate a new pair of keys for your host. You can use openssl genrsa -out ca.key 4096 and openssl req -new -key ca.key -out ca.csr to do this.
Human: Okay. done!
AI: Next, use openssl x509 -req -days 3650 -in ca.csr -CA ca.crt -CAkey ca.key -set_serial 01 -extensions v3_ca -out ca.crt to convert it to the proper format. Finally, copy the contents of the ca.crt file to the correct directory on your server.
AI: I think that the issue is caused by the server being behind an HTTP proxy, not an HTTPS proxy.
AI: Can you try accessing the server directly instead?
Human: I see the Apache default page
AI: Can you open the webpage using curl?
Human: Yes, it works
AI: Can you try a different TLS version?
