Apex legends prediction error everytime i move

Hello , i am facing this in game lag issue ,there is a pridicton error symbol showing all time due to wich i rubber band like hell and i cant play game .

i have tried every possible thing wich EA asked me like 

1.CLEAR ORIGIN CACHE

2.CLEAN REGISTRY, CLEAR CACHE AND TEMP FILES

3.FLUSH DNS CACHE

4.RESET HOST FILE

5.CLEAN BOOT

Also i asked ISP to remove Unknown host but he said he can't as ip has to bounce from those host's

can you help with some solution so i can play Apex without any issues.

thank you.
