I want to allow eager readers to sign up on my website to receive emails from me. I have a MailChimp account and my WordPress expert told me it would take five minutes to install a plugin that uses it.
Yeah, right. Not for me! I installed the plugin and supplied my API key and got this message:
“Uh-oh, we were unable to verify your API Key. Please check them and try again!
The server said:Could not connect (ERR 13: Permission denied)”
Frustratingly, a couple of people logged the same issue on the WordPress forum over a year ago but never received a reply.
I tried another MailChimp plugin – same problem.
The solution lay with my hosting provider. They block outgoing connections by default, but you can add them to a whitelist. Once I did this the problem went away.
