   Solution 4:

   Part of the reason is depending on your system and router. Now routers are generally less problematic. Most of the reasons are system reasons. If your system is a personal modified version, those are not official. The approved version, after connecting to the VPN, will also be automatically disconnected, or an error occurs. We strongly recommend that the system use the official version and not use other unofficial versions.
