Find all primes p and q such that p2+7pq+q2 is a perfect square.

One obvious solution is p=q and under such a situation all primes p and q will satisfy.

Further if p≠q then we can assume without the loss of generality that p>q. Assuming this and that there exists at least one such perfect square I have tried to show some contradiction modulo 4 as any odd perfect square leaves a remainder of 1 when divided by 4, but it is not working. However I firmly believe that p=q is the only solution, but I have failed to prove this.
