I feel really stupid writing this. I was trying to set up port forwarding for a UDP service (a Minecraft Java server using Geyser to play with friends on Bedrock). I set it up correctly on the router and started the Geyser server on port 19132. I looked my public IP up. I tried joining through a Bedrock client… no luck. I spent a good while on trying to fix it before I realized that had Cloudflare WARP enabled, so I was using the wrong public IP address…
