Can I use an HTTPS proxy URL with Web App Server without enabling SSL?

I am looking to set up a reverse proxy to connect to MATLAB Web App Server. I would like my users to be able to access the server through a secure (HTTPS) proxy URL. However, I have not set up SSL for my Web App Server.

Can I use an HTTPS proxy URL if my MATLAB Web App Server is still using HTTP?

This is not a recommended workflow, as it can cause WebSockets errors and performance degradation. Mismatched protocols between the proxy and the server may result in errors such as:

• WebSockets protocol was not established. This may cause performance degradation and occasional errors. Contact your System Administrator.
• WebSocket Exception: Cross origin websocket handshake request
• Secure Connection Failed (SSL_ERROR_RX_RECORD_TOO_LONG)
• 502 Bad Gateway 

Ensure that SSL is enabled on your MATLAB Web App Server prior to configuring an HTTPS-based reverse proxy. Refer to the following documentation for instructions.
