Here anyone knows how to fix below given problem?
Serve resources from a consistent URL
I think this is being served by AdSense. If that is so, you should not worry about it.
But why Adsense is serving from different TLDs
Are you using Auto Ads? I think that could be a reason. There is no fix, except removing.
I am using Vignette Ads only
Disabling Vignette Ads solve the issue?
If you are using Adsense, then probably you can ignore this warning.
