Something went wrong: cURL error 7:

Are you getting this error when activating Plugin ?

Can you see Settings > Blockonomics menu

I already activate Plugin, and it just error when i press “Test Setup”

This error hints to a firewall blocking outgoing curl calls

If you are testing on localhost – Make sure you lower your firewall settings

If you are testing on a hosted server – Note that some hosting providers block outgoing curl calls. You should contact your hosting provider to relax this
