Seems main issue is with my ports
Here is my port setting progress
I am using wrong:
Address?
Port?
Added the Port forward incorrectly in my router?
Go to:
Device Settings > Troubleshooting
Scroll down and find the ADB Port.
Copy that ADB port number.
Paste it into the port input field on the browser page.
If the connection is successful, it should show a completed connection message and open an additional terminal window.
If you want to check it manually, you can also use ADB like this:
adb connect 127.0.0.1:<MuMu_ADB_PORT>
adb devices
adb reverse tcp:9999 tcp:9991
Replace <MuMu_ADB_PORT> with the ADB port shown in MuMu Player.
The important part is that MuMu’s internal agent uses port 9999, while the PC server uses port 9991, so the ADB reverse connection is required for the server flow to work correctly.
Additionally, if you are using a router, you must configure port forwarding. TCP port settings are required.
