Can't access most of the websites after connecting to globalprotect VPN on Linux

siddhantgarg — Sat, 23 Apr 2022 16:38:19 GMT

Hi,

I have installed GlobalProtect_UI_deb-5.2.4.0-14.deb using the command 'sudo dpkg -i GlobalProtect_UI_deb-5.2.4.0-14.deb' on my Ubuntu system. Then I am using

$ globalprotect

$ launch-ui

connecting to the portal.

But after connecting to the VPN I am not able to access most of the websites like Github, Stackoverflow, and many others.

Below are some of the checks I have performed based on other similar discussions. Please let me know how can I resolve the issue. Thanks,
