Hello Nicola,

This issue is primarily seen in Central ZD and remote AP kinda deployments. Is it the case for you too?

MTU changes primarily take place AT router apart from ZD.

Best of Luck

OK, that's good to know.

So it was switch limited? Did you have to shorten it?

The problem was MTU miss-match between ZD and AP.
