How to fix Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch java?

Question

Java

application.properties Procfile
server.port=${PORT:32500}

web: java -Dserver.port=$PORT -jar front/target/front.jar

It worked ok, but now Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch java
Push and deploy don't help, stop and restart too, deleting app doesn't help.

Answer 1

The choice of another viola helped. port server.port=${PORT:33500}
