start simple. make sure UPnP is checked in your router if not select and apply. if it is deselect it>apply the change>re-select it>apply the change> power cycle router.
it is on it also shows some ports for e.g. used by xbox live services checker in windows 10 settings "teredo". mp isp told me to put ports in port forwarding as well as enable dmz but not working dont know wth is happening so frustrated
disable the DMZ and clear the ports you have in port forwarding, you want everything to be back the way it was. Next can you tell me what kind of router you are using? Also, are you using the windows firewall? if you answered yes that you are using the windows firewall you may need to make an exception for the program . instructions here:

Once you saw that UPnP was on, did you turn it off and back on again and then follow up by power cycling your router? if no, do that. Lastly, don't forget to tell me the make and model of your router.
