Route10 crash sometime

so i decided to reset my route10 to have better loadbalancing

but i encounter some issue to it

-first issue most of the time i change some setting it will loading and sometimes disconnect to the cloud ..sample change other port to wan port after i click save it will loading i wait for few minutes but wont comeback until i reboot but the setting wont save…

i dont know why but my loadbalancing now is kind of become much better went i did not set my main isp to static.. i add my static ip to another router connect it to route10 as wan dhcp become better in loadbalancing..
