Hi im currently trying to find a way to switch out the protocol of a url. Im having a server wich is running fine on its own but behind a apache reverse proxy its throwing the error connection to websocket failed. The problem is that the Websocket is only locally available as wss:// through the ip of the server it gets switched to https://. Is there any way to switch it back ok a apache reverse proxy?

You don't want to switch protocols. WSS and https are two different protocols - for a reason. If your app requires wss it requires wss.

What you want is to configure Apache to proxy https and wss for you. That can be done with mod_rewrite. Add something along the lines of the following to your vhost stanza:

ProxyRequests Off    
RewriteEngine On
RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteRule /(.*) wss://localhost:8123/$1  [P,L]

That sounds like a bug in Unraid, so you should probably ask them to fix that bug.

If frontend and backend of a product doesn't agree on what protool to use, it's a bug.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
