Help FEL Loader Valve Connection Leak. How do I fix it?

[RomeK2]

My BX23S has a fluid leak at the coupler where the front loader valves connect. I cleaned it very well so I can see where the leak is coming from. It look like it leaks from the connection because there is a puddle on top of the lower block (the lower block has the nut on the 1st picture). Also, it looks like it leaks from the fittings below the lower block (above the white and yellow valve covers on the 2nd picture).

If you are a BX23S owner, have you had this happen on their BX23S and what was the fix? or Any suggestion of a fix from your experience or knowledge?

I've attached a couple of pictures but I am not sure you will see the fluid as it is very clear (clean).

Thanks.
