unable to connect 2 app 2nd sim network

i am facing a unique kind of problem.

Here i am using dual sim android phone. Usually i use internet from sim 1 but for last 2 days i start using internet from sim2. Now when i change back and start using internet from sim1 I found my whatsapp, emao viber not connecting internet. All other app and browse working perfectly. I tried many possibilities including uninstalling application, changeing sim slot many time restart etc..no hope

Once i connect that 2nd sim this app again work normal.

Please if anyone come across this problem ..help me
