Internet connection might be down. Sleeping for 10 minutes.

Hello!
VirtualBox + linux mint + whonix gateway = Traffic does not go further through the inward gatevay. It gives an error:

“General Timeout Error. Internet connection might be down.
Sleeping for 10 minutes.”

https://www.whonix.org/wiki/Non-Qubes-Whonix_Known_bugs#Suspend_.2F_Hibernate_Issues - Does not solve the problem.

Running time syncronization monitor does not fix the issue. Differences on the host are not more than 5 minutes. I sure that my host’s clock was set at the correct time.

What should I do? The Internet does not go any further because of this problem. Thank you!
