No internet connection on WSL Ubuntu (Windows Subsystem for Linux)

Recently I installed **WSL Ubuntu 18.04** on my Windows machine, but nothing seems to work properly, because I have **no internet access**.<br> I tried a few commands and `sudo apt update` says 'Connection failed' and `ping google.com` literally takes forever as you can see in this screenshot: ![][1] [1]: https://i.sstatic.net/NXJNx.png<br> <br> I also checked `nano /etc/resolv.conf` and made sure that the nameservers are right, completely disabled Kaspersky and its firewall, disabled Hyper-V, reinstalled WSL a few times and even disabled Windows Defender. Nothing helped.<br> <br> So do you have any ideas what the issue could be here?
