    • openHAB version: openhab-3.1.0

  • Issue of the topic: I dont understand why openhab is runing but i cant enter at localhost:8080, i was look at log and see this:
    2021-11-22 03:48:23.585 [ERROR] [.service.internal.HttpServiceStarted] - Could not start the servlet context for context path [] Failed to bind to /
    Caused by: Address already in use: bind

i some googled, but not understand, where is my trouble.
I must change windows hosts file?
I look at java.exe process and what ports he use many ports.

You probably have another application running that has already bound to port 8080.

Run sudo lsof -i TCP -P | grep 8080 to see what process it is.

Edit: saw that you are using windows, then use netstat -abn -p TCP and look through the list.

Thank you, that was what I needed!
