random disconnect inside dungeon, no error code, internet is fine

[gumas]

i dont know what to do with this, it happen everytime i went to dungeon/trial/raid.

just doing my stuff and then i got disconnected, the thing is there is no error code, no lag/delay, nothing. it was smooth run then suddenly screen goes black and i got "returning to login screen" tooltip.

i got thrown back to startup screen (the one with stormblood logo) then i relogin back again, and everything normal again. 10-15 minutes later, it happen again.

i dont know what to do now, when i got DC i check my connection, everything is fine on my ping prompt, not even one pip of RTO, my speed didnt go down too. pls help

update: it seems indeed only happen when iam inside dungeon, doing all beast tribe just now and everything is fine. i try other online games like CSGO, GW2, WOW and everything is also fine, so at least i know the problem is with the FF14
