I have a Note 4 but experienced the same issue. After the last update (android 6.0.1) I started getting error 495 on many apps. The issue happened only on Wifi.
A few weeks later my Galaxy Tab S (T800) got the update to 6.0.1 and ... damm.... error 495
I tried everything and ended up factory resetting both devices. However, it didn't help.. issue was still there.
Later I figured that it has related to my home WiFi only. No error 495 at work.
After reading this thread I enabled IGMP on my router (netgear wndr3400) and things got better. Error 495 was still present but on much fewer apps. Yesterday I changed the DNS on my router, from 8.8.8.8 to the automatic DNS provided by my ISP. Don't know how, but that seems to have fixed it... all the problems are gone.
