Server error remove that is inet again then it would have to go again. Or put the router out

The message comes with only if the Internet connection is too bad. Times an Internet connection test and then try it again. If it still does not work, then connect you again with the wireless router.

80% indicates my internet connection. Restart router did not work.

I already did everything.

Now I've synonymous habs synonymous tried if you have the inet setting manually mavhst and what wrong set then works fine gscheid in me then all the same message.

You have to disconnect the Ps4 again from the internet. And then connect again.
