the resolv.conf file within the „/run/“ folder has no effect, because it is created during runtime. The resolv.conf in „/etc/“, though, is the file your device receives from your router to save information about your last connection. As your router cannot resolve „max2play/“, it seems it didn’t find your Max2Play device within the network. We don’t know much about your router and how it handles DHCP (dynamically providing IP addresses in your network) and cannot provide more detailed information, sorry. You could also contact the manufacturer of your router device about this issue.
