Pokemon go unable to authenticate

[Salman460]

I've been playing Pokemon Since It came out but now suddenly it doesn't log in On my phone only
It keeps saying unable to authenticate try again later but If I login with my mother's phone it works

Server issues. Your phone is probably trying to connect through a different server than your mom's is. It happens to me every once in a while.

If your pokemon game work at ohter device, it means your are not banned.

I've been having the same problem, haven't been able to log in for weeks. Seems like ever since the buddy pokemon update. I just tried the above solution posted by Sevarc and it did not work for me. Still getting unable to authenticate.

Can you log in from another device?
