hi @ganeshjadhav  - could you expand on the details of your network setup please? 

 - Apart from the MX what else does your network comprise of - what's downstream of this device - switches, AP's?

 - How are you clients connecting - wireless, wired?

 - where are your L3 Vlan interfaces configured - switch/MX?

 - What DNS are you using and where does that service reside?

 - if you have two WAN/ISP's are you load balancing between the two?

 - have you tried isolating one of the WAN connections to see if its a particular one giving you issues?

 - what troubleshooting steps have you taken thus far.....?
