Step 1: define the app listening port
Once your Custom plan is active, predefine a default listening port directly in the app.properties file.
Define ports
Here's how to predefine your default listening port in the app.properties file:
- Open Multilogin
- Go to “My account”
- Click “Open logs directory” – this will open the folder
/.multiloginapp.com/logs - Navigate one folder up to
/.multiloginapp.com - Use any text editor to open
app.properties - Add a new line to specify the port number:
multiloginapp.port=35000 - Save the changes
Make sure the port number is between 10000 and 49151.
You can also find the app.properties file in the .multiloginapp.com folder:
- Windows:
C:\Users\%username%\.multiloginapp.com - Linux:
/home/%username%/.multiloginapp.com - macOS:
/Users/%username%/.multiloginapp.com
The folder may be hidden, depending on your OS settings. To display this folder on Mac devices, you can use the following keyboard shortcuts:
-
Cmd + Shift + H– to display the current user's folder -
Cmd + Shift + .(period) – to display hidden folders and files
