Geyser could not open its Bedrock port
Applies to Geyser, Paper, Velocity, BungeeCord.
What it looks like in your log
Failed to bind to 0.0.0.0:19132
What causes it
Geyser needs UDP port 19132 and could not bind it: something else holds it, or the host only forwards TCP.
How to fix it
Open and forward UDP 19132 (or change bedrock.port in the Geyser config) and make sure only one Geyser instance uses it.
