you say disable firewall in the router (client side) or in mikrotik router?Just as a test (I realise this is not a solution)....
Can you open the firewall so that no packets are dropped. You'll have to do this on a MAC and IP Layer... (so it will be a allow any from any via interface). Also considering it seems like a bridged interface, I'll also look for things possibly being dropped on the bridges...
Perhaps something is dropping the broadcasts (or related) packets coming in / going out of the router... Looking at the debug log you pasted, it looks allot to me like the clients is not receiving the ACK Broadcast from the DHCP Server....
Al ready found a sollution ?i disabled all mikrotik's firewall rules... and .... everything is ok in the last hour
i will monitor the connection a couple of hours and then i will turn on rules one by one and see which one is disturbing...
Thank you savage for your help... and then i will post the annoyance firewall rule.

Ive got the same problem. But when i disable all firewall rules the problem is still there. The problem is related to the LAN interface. But when i make a VPN Connection the problem isnt there.
Proxy-ARP is enabled on the lan interface
Disabled Proxy-ARP and working DHCP
Enabled Proxy-ARP still working DHCP
Reboot for check
Problem is there again. For now disabled Proxy-ARP and everything seems fine
