Spring Boot fails to start: Port 8080 already in use, taskkill access denied on Windows [closed]

calendar_today May 27, 2026 person Josue Paniagua domain spring-boot
I am trying to run my Spring Boot application on Windows but it fails with this error: Web server failed to start. Port 8080 was already in use. I tried to find the process using the port: netstat -ano findstr :8080 Result: TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 8580 Then I tried to kill the process: taskkill /PID 8580 /F But got: Error: Access is denied.
