I am trying to access my localhost server from Parallels Desktop and facing some issues. For example, I have an app on Spring Boot that runs on port 8081, and running sudo lsof -PiTCP -sTCP:LISTEN in Terminal gives me the following output: java 8168 username 107u IPv6 0x53524f3d71f26ae5 0t0 TCP *:8081 (LISTEN) And the output for second application (not Spring Boot, but Spring inside Tomcat 7) is: java 7756 username 504u IPv6 0x53524f3d6cfe6fa5 0t0 TCP localhost:8096 (LISTEN) I can easily access the first application from Parallels Desktop by address http://10.211.55.2:8081/, but doing the same for http://10.211.55.2:8096/ gives me this site can't be reached error message. So, how can I run my second application on *:8096 instead of localhost:8096?
