Today after I turn on the global VPN function of Linux version Geph 4.4.20 client, I can not open any webpage on Ubuntu 18.04

Today after I turn on the global VPN function of Linux version Geph 4.4.20 client, I can not open any webpage on Ubuntu 18.04. I run Linux version Geph 4.4.20 from Ubuntu 18.04 terminal. After I turn on the global VPN function of Linux version Geph 4.4.20 and click the connect button of Linux version Geph 4.4.20 client, Geph 4.4.20 needs administrator permission. I use TCP mode. Today after I turn on the global VPN function of Linux version Geph 4.5.0 beta 1 client and click the connect button of geph 4.5.0 beta 1 client, geph 4.5.0 beta 1 client program automatically quits. I use Linux version geph 4.5.0 beta 1 client on Ubuntu 18.04. Linux version Geph 4.5.0 beta 1 client is a APP Image file. I run Ubuntu 18.04 in VirtualBox. I upload the geph 4.4.20 debug log file. Could you please solve these problems? Thank you very much for your help. I really appreciate it
