Decided to try out Palace of the Dead for the first time today with a friend (In Tonberry). For some reason, I seem to disconnect from the server with error 90002 after less than a minute. When I'm doing solo, it disconnects more frequently making the instance unplayable. I've already checked my internet connection and pinging the server I'm on and no problems so far. Haven't actually encountered any disconnections in the Overworld so far either from the time I've played. Duty Roulette and other quest instances work fine as well.

I've tried pinging the server and using trace route and seems to fine, albeit high latency due to me being in Oceania. Command prompt prints are as below:
