\[ \boxed {y^{\prime }+\frac {\ln \left (x -1\right )-\coth \left (x +1\right ) x^{2}-2 \coth \left (x +1\right ) x y-\coth \left (x +1\right )-\coth \left (x +1\right ) y^{2}}{\ln \left (x -1\right )}=0} \]

Solution by Maple

dsolve(diff(y(x),x) = -(ln(x-1)-coth(x+1)*x^2-2*coth(x+1)*x*y(x)-coth(x+1)-coth(x+1)*y(x)^2)/ln(x-1),y(x), singsol=all)
