Word.ai API error when trying to connect to Static Page

API not working, when I trying to connect Word.ai to SEO Content Machine Static Page. Error is:

Warning spin: Word Ai error, wai.wordai.com - 504 Gateway Time-out “\r\n504 Gateway Time-out\r\n<body bgcolor="white">\r\n

504 Gateway Time-out

\r\n
nginx/1.14.0 (Ubuntu)\r\n\r\n\r\n” retry 1/4 in 16s

504 error means WordAI servers are busy and can’t accept the request.

SCM will retry the same request up to 4 times before failing.

If it fails 4 times, I would contact WordAI and see if they are experiencing an outage.
