Found Fix
Run following command in Terminal

sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"

(Allows processes to send packets to gameserver which are typically blocked when running via containers. Second number can be a value as high as 2147483647 as that is the largest value in a 32-bit integer, though any lower value is also okay.)

Afterward error should be fixed.

Unfortunately changes made reset after system restart, so command will need to be entered after each boot.

To make the net.ipv4.ping_group_range="0 2147483647" setting persistent across reboots:

Create a file in the /etc/sysctl.d file with a text editor: sudo nano /etc/sysctl.d/99-ping-fix.conf
Add this line to the file: net.ipv4.ping_group_range = 0 2147483647
Save and exit the file.

Then, apply the change immediately: sudo sysctl -p /etc/sysctl.conf

Check that the setting has stuck:

Run: sudo sysctl net.ipv4.ping_group_range it should print out 2147483647.

Now your setting will persist after reboots!
