It's probably just due to a slow/unstable wifi. I get that error quite often as well. Trying to relogin again and again usually fixes it after 2-3 times. It takes time but it is better than nothing :)

p.S. Try to relogin into raids from the shop instead of the underworld map. That usually works for me.
