I get the message that my site is unreachable on my Jetpack settingspage and when I try to connect to Facebook on my settings page. Here is a screenshot: https://2fel.info/jetpack.png
I have increased php_value memory_limit and WP_MEMORY_LIMIT to 256M. I have also tried removing (deleting) the Jetpack plugin and reinstalling it. I never had any other plugins on this site.
I also have nothing in my error log.
Do you guys have any ideas?
Thanks in advance!
