Everytime i leave the map and come back it wont let me access the obelisk or do the volundr forge activity help?
The forges are on daily rotation of Volundr-Gofannon-Izanami-Bergusia. Today is Izanami. As for the Obelisk: there are workarounds such as fast travel back to Gulch as many times as necessary until able to interact. Going to orbit and back may also help.
