Lesson 6: I can't "verify" by VPN.

[frank0532]

when I run the "scripts/deploy.js" without "verify" well but error as below with "verify":

NomicLabsHardhatPluginError: Failed to send contract verification request.

I think this is because of "using VPN"( without it I can't connect the other web);
I also try to verify on "ethscan" but I some time I get below error:

@frank0532 Push your code to GitHub and leave a link here. We will check import issues and let you know whether it is a VPN issue or any other.

@frank0532 : ^ Exactly!

@alymurtazamemon I have push code: https://github.com/frank0532/test_verify
Thanks a lot.

probably you forgot await before verify function on 01-deploy.js file
