Connection Problems to lan over Wireless Connection.

I am having some problems and I can’t figure any solution.

I can connect from a network device from lan B to lan A without problems.
Also I can perform bandwidth tests from lan B to lan A.

From Lan A I can ping lan B and other lan devices but I can’t access from winbox the router B. Eitheir I could not make bandwidth test from the mikrotik winbox.

In the first picture is the error message i am getting when I am trying to connect to the lan B mikrotik.
