Change Optigo Capture Tool management port (default 4000)

If port 4000 is used by other applications on the machine on which the Optigo Capture Tool is installed, you would need to change the port to another number in order to manage and configure the Optigo Capture Tool.

To verify if the Optigo Capture Tool is indeed conflicting with another application, look at the latest "node.exe" log file in:

C:\Program Files (x86)\Optigo Capture Tool\data\log

If you see this line at the end of the log file with the following text, then it confirms port 4000 is indeed used by another application.

2024-06-14T07:10:41-07:00 [ERROR] Port 4000 is already in use by another application. Currently CaptureTool can only listen to port 4000

The Optigo Capture Tool GUI management port. To do so:

1. Open Notepad in administration mode
2. File->Open. Change the allowed files to "All files (*.*)"
   
3. Find and open the following file C:\Program Files (x86)\Optigo Capture Tool\zephyrus\server\index.js
4. Find the word (CTRL-F) 4000, and replace with 4001 (or whatever port you wish to use)
5. Restart the Optigo Capture Tool in Windows Services 
6. Open your web browser, and now go to https://localhost:4001 (or replace 4001 port with the port you used)
