Mobile Phone Hotspot not letting me play multiplayer games

Fix

Go to Settings > Connections > Mobile Networks > Access Point Names... Tap the existing entry to open it and screenshot or make a note of the settings.

Go back to the precious screen, Access Point Names... click ...Add and give it whatever name you want. Mimic the settings you took note of but change APN Protocol & APN Roaming Protocol to IPv4 Tap the 3 vertical dots at the top and hit save. Now select your newly created Access Point, your service should disconnect then reconnect.

hope this helps other, worked for me for league of legends 

if this don’t work try setting APN Protocol & APN Roaming Protocol to IPv4/IPv6

If this helps any one post your outcome with the name of game your playing

maybe some one can buy this old wounded warrior a meal (will Code For Food) :P
