Pso2 authentication error

So you just need to configure your internet devices now.

They are unconfigured, so have access restrictions, causing these errors.

If you do not have knowledge, I advise you to contact the ISP that they will do for you

set a fixed ip for the console/PC, open the ports described below, disable and enable the UPnP function and disable the modem firewall, if you have a modem and a router the process has to be done on both devices.

Put console/PC IP in DMZ zone.

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

Port 500 (UDP)

Port 3544 (UDP)

Port 4500 (UDP)

You can ask ISP(Internet Service Provider) for help

Mario, usually authentication error is due to a network problem, let's check

You will have to log in your accounts again, that's all

Press and hold the power button on your Xbox for 10 seconds, wait for it to turn off. Unplug it. Now wait 1 minute before turning it on.

Open the panel by pressing the Xbox button in the center of the controller.

Scroll right on the panel to the System area.

Select Settings.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this JTSHOTU

When you say "PSO2" are you referring to Phantasy star online 2?

In any case. I can advise you some things but if the issue persists you may need to reach the game developer if you're experiencing this only with this game.

First, did you tried using a completely different wifi network?
For example sharing mobile data via wifi hotspot and connect your console in that way

Or, what about using a different DNS address
go to Settings > Network > Advanced Settings

Once you’re inside the Advanced Settings menu, go to DNS settings and select Manual from the list of available options.
When you get to the next screen, enter 8.8.8.8 in the box associated with the Primary DNS and 8.8.4.4 in the Secondary DNS box.

Once the default DNS addresses have been changed, restart your console and see if the issue has been resolved at the next console startup.

(If that doesn't work use 1.1.1.1 as primary and 1.0.0.1 as secondary)
