Oh, wow. I cannot add more than a vote for your time and patience, thank you!

revised Diophantine equation: $x^2+y^2+z^2=n(xy+yz+zx)$
Two typos, $X^2 \equiv 2-3$ to $X^2 \equiv -3$ and the equation of $C$..

@YongHaoNg Your completion of squares is a known technique, but here it looks magic. I checked term by term, and it is correct. Can you show us in detail how you obtained it?

Indeed it was assumed implicitely that $x\ge 1$; in rough terms, half problem is missed, i.e. all cases $x\le 0$; except that, we are talking about trivial cases.. I am still waiting if someone finds a elementary solution different from mine
