Upgrade network doesnt work - Could not resolve host - Pro Sites

Warning! Problem updating http://maklare.xxx.se. Your server may not be able to connect to sites running on it. Error message: Couldn't resolve host 'maklare.xxx.se'

How to fix this? I have disabled domain mapping and multi domain plugin because I not going to need them yet.

I have WP 4.0 Multisite Config and Buddypress + Pro Sites
