An unexpected disconnection occurred

Hello.
Game: POE2
Character: QonliFans, lvl 84 Blood Mage

While doing maps, I encountered Abyssal Depths, cleaned it up till the boss, and TP'd back to the surface, then to my Hideout. Then, I teleported back to the map and then entered the Abyssal Depths again. Inside, I used checkpoint to TP to the center, and got disconnected. Since then, I cannot log into the game, getting "An unexpected disconnection occurred" after choosing my character.
