Freedomfi 5g Mining with Nighthawk

Anybody on here Mining helium and have a nighthawk C7000v2 Modem/Router? Im trying to onboard my Miner and It wont work. It keeps saying I have an internal server error. I port forwarded 44158 and im wondering if there is anything else I need to do to let traffic run to and from the miner uninhibited. Anyone out there have any advice for me?
