Error Response: Server-related issue

Solution: Hit up the PSN Status Page to see if there is any problem outlined by Sony. Restart the PS5 and used a wired connection to access the Internet, then configure your settings again. Go to DNS settings in the Network Settings and configure your settings with the number of public DNS that is free and open to the public by companies or organizations. Unplug your PS5 and plug it back. To turn on the PS5 into Safe mode, Press and Hold down the power button on the Playstation 5, until the console beeps twice. Connect your controller with a cable and select "Rebuild Database". If this doesn't solve your problem, try contacting Sony directly or a video game repair shop for further help. Please post below if you were able to solve the issue yourself to help others.
