I am getting this error after restoring a database backup on my test site (wheat-free.com). I do not use any cloud services, and my firewall is not blocking you. What could cause this?

Your site there is currently showing an access denied message, which is what will be causing that issue

Hi Marc, I can assure you that the block was gone when I tried to connect yesterday. It's a simple .htaccess block to my test site, and when it was removed yesterday I was unable to access marketplace, and got that error.

Today, after clearing various caches and removing the .htaccess block I was able to connect.

Thanks for following up!

Glad to hear that your issue is resolved and you were able to connect!
