Having trouble getting a web application that uses websockets to work after setting up the HTTPS Apache reverse proxy to Tomcat
I have a web application that uses a WebSocket connection.
I set up a Ubuntu droplet and configured Apache and Tomcat.
My application was working fine until I tried to setup SSL.
I followed the instructions to get an SSL certificate, and followed the instructions in the following post to set up the Reverse Proxy with Apache:
How To Encrypt Tomcat 8 Connections with Apache or Nginx on Ubuntu 16.04
Now, SSL works fine, but it complains that you can not start a ws:// from an HTTPS connection.
So I tried changing the call from ws:// to wss://, but the WebSocket will not connect, because it can’t properly upgrade the protocol from https to wss.
I am relatively new to the unix world, and am not familiar with all of the Apache and Tomcat configuration parameters.
Can someone please let me know exactly what I need to configure to get Apache to properly proxy the wss to Tomcat, and/or what Tomcat configurations I need to make to get a secure websocket working with this Reverse Proxy setup?
