Hi, I'm new to the forum and I don't have much knowledge in networks and in mikrotik.
I have a Mikrotik Hap Ac Lite Router works great in both the 2.4 and 5.8 bands.
The problem is when I want to run Chromecast 3, it is set up perfectly with the 5.8 band but when I want to play it doesn't recognize it.
Now if I configure it in the 2.4 band it works perfectly and likewise if I connect to the 5.8 band it works fine.
But as I said before if I configure Chromecast in the 5.8 band and connect to that same band it does not recognize it.
It is configured as it comes from the factory, I do not use CapsMan.
I hope you can help me, thank you very much

Are you getting anything in the log when on the same band and attempting to cast?

Default forwarding.
