Hi Nguyen, 

Sorry for late reply and your quick reply. I was too busy last weekend. I got it on Sunday. The problem is that for the server address, I put 192.168.1.70. Actually for I host it on localhost, I should put 172.0.0.1. I am new to this network system. 

Thank you very much!

If i run ps aux | grep 8080  it looks like a lot of things are using 8080

I am using the 7.0.3 . I host the mysql server in Docker. I put following things on the configuration page and "check connection" is OK. When I try to set up. The terminal will give me 8080 was already in use error.

Hi, I encounter same issue on Mac.

 ***************************
APPLICATION FAILED TO START
***************************

Description:

Web server failed to start. Port 8080 was already in use.

I have done port scan and I am sure the 8080 is not occupied.

I then change the conf/application.properties from 8080 to 8082 but it gives me same error.

Any help?
