If you dial up the Internet in your own home, the port 1935 you mentioned is actually a registered port (the port number ranges from 1025 to 49 15 1), which is based on the nature of the port. If it belongs to the TCP protocol port according to the provided service mode, it will be opened.
Okay, let's get down to business.
1. Enter the control panel, open the network connection, right-click "Local Connection" in the pop-up window, and select the "Properties" option to pop up the local connection properties window; Open the General tab, select the Internet Protocol (TCP/IP) option, and then click the Properties button to open the Internet Protocol (TCP/IP) property setting page.
2. Continue to click the "Advanced" button on this page to open the advanced TCP/IP settings window, select the "Options" tab, select "TCP/IP Filtering" in the "Optional Settings" item of this tab, and then click the corresponding "Properties" button to open the settings window.
3. As the aforementioned port 1935 belongs to a TCP protocol port, you only need to select "Allow All" in the setting item corresponding to "TCP port". If you know which ports you don't need, you can also check Allow Only to add the ports you want to use. After setting, don't forget to click "OK" button to make the setting take effect.
If it's a firewall problem, you just have to open it at the firewall.
