Just a heads up if it is not known, ScreenScraper had some issues it appears. There system went down for a bit like a month ago for nearly a month.
Also if anyone never noticed if the CPU load goes above a combined 100% for the 2 they have non-reg users are locked out and I think if it gets high enough only contributors are allowed which is above registered users, and reg users are above non-reg users.
Over the past month or so, they have had such issues that it was basically closed to all non-reg members while they repair or correct issues. It looks though that is is back up and working as it was before, allowing all to scrape.
But another thing that can get you blocked from scraping is it you scrape more than I think several thousands of items in one day. That can get you blocked for some small time period, a day or 2 I think.
So it is not an issue with Batocera it is an issue with the website that no one on here can correct, visit the website on a browser to know if your message you may be getting is because of something with the website, maybe CPU load is too high even if website is up and running well, Batocera seems to just give access to the API it does not control the API.
