Question Lagging on low ping

[Soloontop]

So i play fortnite and recently i've been getting connection error symbols, usually yellow and red x's. From my experience, they usually indicate high ping or high percentage of packet loss but whilst gaming i'm on 0 ping and have 0 percent packet loss. But I can definetly feel the lag, during the yellow x it feels a bit delayed and the red x is so laggy. I tried restarting my internet, deleting and reinstalling fortnite, and reinstalling NIC drivers. I thought it might've been my internet but I dont seem to lag on any other games. Is the problem the game?
