Yeah, I kind of guessed that relationship, which is why I checked my spelling about 30 times. The declaration is definitely there, and it definitely matches your guide word for word and in the same case. As does the custom dial string.
I am fairly sure the oauth is working too, as the first go around I mistyped the clientID and the secret and got a ton of errors in the log at startup. They all went away when I fixed these.
I did try moving the stuff around again in the two conf files to no success. Still getting the same error about the gvsip1 endpoint not found.
