Solution 2. Enter username and password to access the internet

PS4 error SU-35931-1 may also be caused by the security property of the internet access point or your internet service provider (ISP). Some access point and ISP require you to log in first before letting you access the internet.

To log in, open the PS4 internet browser to a webpage, which requires you to input the username and password or use PS4 User Guide.

If you do not know the username and password, call your ISP. If you do not own the network, ask for the IT administrator of that access point. This is common in school campuses and offices.
