Hello, let me see if i can help you. First of all try following the instructions in the [url=https://www.bungie.net/en/Support/Troubleshoot?oid=12915]Network Troubleshooting Guide[/url]. If you still have issues, try the following steps: -Disconnect your ps4 from Network, than connect your ps4 with a new Network, but use your Handy hotspot, from your Phone. -If you dont know how, please google the steps with you phone.. -After your phone is connected to your PlayStation, start destiny 2 and try logging in. -After that try to connect the system back to your home network and start destiny 2 again. [u]If it still not working with your Homenetwork, you have to initialize (hard reset) your Playstation system.[/u] If you have to do a hard reset on you ps4.. all data will be deleted, but you can back up data from offline games in the ps + cloud and save clips and images to an external hard drive.
