Download queue - Invalid host

While trying to download some chapters off MangaDex, I encountered these error messages (see screenshot). Don't know if it is a serverside issue on behalf of MD or some MangaDLR issue. It hasn't been possible to download these chapters at all, while other chapters have downloaded without any problems.

Series is Zutto Kitto and chapters in question are done by BL Dot Cum if you want to check for yourself. Latest version is in use on an Android device.
