Although the RE NET servers are operating correctly, we have confirmed that the “Cannot connect to RE NET” error can occur on PlayStation 4 when using a less than optimal network connection, particularly when using wireless networks.
A game update to improve connectivity is currently being considered. In the meantime, if you are using a wireless connection the issue may be mitigated by taking the following steps:
- Switch to a wired connection if possible
- Reboot your router
- Change your router's wireless channel
- Move your PS4 closer to your router
- Remove any obstacles between your router and PS4
- Avoid using electronics that can cause interference when playing, such as microwaves and other wireless devices like smartphones
- Disconnect all other devices from the network when playing
RE NET sincerely apologizes for this issue, please wait for an announcement regarding the update if the above does not help.
