System check error after migrating site to new server

We are using Joomla 1.7, Moodle 1.9.x and Hikashop.

We just switched over to a new hosting provider.

I added the new IP address to the XML-RPC hosts list with /32 at the end.

I've checked URLs on both sides -- in Joomdle and in Moodle. All looks OK.

But I'm getting the error: Joomla URL seems to be misconfigured in Joomdle auth plugin in Moodle

Did I miss something?

Double-check URL, and make sure all SEF/multi-lang settings are OK in Moodle if you are using it in Joomla.

??? Where are SEF settings? Language is set to en_us in moodle.

SEF settings in joomdle auth plugin in Moodle.
