I play on PC. For about a week now I've been getting constant disconnects with either both error codes 90001 and 90002. If I try logging back into the game I get lobby error 2002 and the game closes. If I relaunch the game I can get back in.

This happens in instances and in the overworld, my internet connection outside of the game is fine and nothing else disconnects at the same time. The disconnects can happen anytime from minutes after logging into the game to an hour after logging in. I am connected to my router via ethernet cable and have tried connecting to the modem via ethernet cable with no change. I have contacted my ISP and they can't detect anything wrong.
