With the latest version of JFBConnect 9.0.170 in auto-tune I have:
Could not fetch application and recommendation data from SourceCoast.com. Cached values were loaded, but may be out of date.
It's highly recommended that you make a successful connection to get the most up-to-date application data and recommendations.
And error check: Checks performed on: www.rikoooo.com/ Error: Could not fetch page. Server returned: Error Code: 503 - Unknown Error
It seems like something on your site is blocking automated checks. Our server tries to imitate a browser, but some firewalls or anti-spam software can still detect that it's a 'bot' and not real traffic. When your server sees this type of traffic, it returns a 503 error.
Unfortunately, there's not much we can do on our end to get around this type of block on your site, but I hope that helps explain. Obviously, I'd recommend testing multiple ways to make sure you're not incorrectly blocking 'good' bots, like google, bing, other crawlers and, of course, real people.
