Update 188.8.131.52 for MCGalaxy has been released, adding support for remote web socket proxies. It's highly recommended that you update your server, or backport the changes if you run a custom copy, so that IP address information is accurate when we switch on the proxy for web client users.
This change allows folks using the web client to continue to play the game online as browsers implement more strict security measures.
You can download the latest release from Github: https://github.com/UnknownShadow200/MCGalaxy/releases/tag/184.108.40.206
