@NinjaXDpro @kingdom5 Because Discord has blocked incoming requests from Roblox (due to request spam caused by faulty scripts), if you wish to make a Discord webhook request from Roblox you will have to go through a proxy.
The good news is the Roblox user Osyris has already setup a proxy server just for that, and the transition is very easy. All you have to do is change your http requests' URLs from
A proxy is a webserver that acts as an intermediary; it sits in-between your Roblox server and the Discord server, and simply relays all incoming requests to Discord and their responses back to you.
The result is that instead of seeing Roblox as the sender of the request, Discord sees that other website. This is enough to fool Discord into thinking the request didn't come from a Roblox game.
Be careful as to not spam requests though, else Discord will also block the proxy and we'll be back to square one.
The reason Discord blocked Roblox in the first place was that people were using it as a way to record error messages. However badly written scripts caused errors over and over in tight infinite loops, resulting in request spam.
Discord is really not the service for this kind of thing. If you wish to record error messages I recommend you search for another service.
