I have tried to set up CAPsMAN having one hAP AC lite and one cAP lite.
I was planning to receive an IP from the hAP AC lite by the cAP lite using a wired connection.
But I can see a lot of errors that hAP offers an IP without success.
If I will remove the ether interface from a bridge on the cap the DHCP client will obtain an IP.
Cap successfully connects and receives settings from hAP.
Here is the CAPsMAN config on the hAP AC: https://pastebin.com/qkKFHNAc
Here is the full export of the cAP: https://pastebin.com/FDSEApz7
Both devices have the 7.1.5 stable RouterOS version
