When I input my details again at the bottom of the page I see
"The form is valid, all the posts should be sent to your Wordpress website in few minutes.
Thank you for your trust. :)" as well as the original "Status: Error" message.

I've not got any security plugins (as it's a test site to test out Satellitor) and the connection originally worked but after about 20 articles, it stopped working.

Curious if I'm the only one to see this and if you have any idea what's causing this issue.
