Good Afternoon

I have received this error in the initial install of wordfence
can you assist?

Thank you

Your options have been saved, but we encountered a problem. You left your API key blank, so we tried to get you a free API key from the Wordfence servers. However we encountered a problem fetching the free key: We received an error response when trying to contact the Wordfence scanning servers. The HTTP status code was [0] and the curl error number was [0]
