Problems with some connecting wifi clients

Hi,

I’m using a CCR1016-12G as a router with an 6.40.5 installed version, after which I have some Apple AP-s in bridge mode providing wifi coverage. I’m having issues with some of my wifi clients, for example Chime Pro doorbell, which can obtain an IP from the Mikrotik DHCP, but will disconnect within 30 seconds. I’ve checked that this is not an issue of Access Points, as if I use a MT cAP Lite, the issue still remains.

I’ve also tested out disabling the DHCP from Mikrotik CCR and configured it on the Access Points, but with no success. In addition I’ve also tested the setup in a different location, where I had a different router for firewall, and everything worked fine. Also, I’ve tested turning off the firewall rules from the mikrotik side, but that also didn’t seem to make any difference.

Has anyone encountered a similar problem with mikrotik and what could I try to resolve the issue?
