How to fix CE-105799-1, easiest first
- Check PlayStation status
Open the PlayStation status page. If there's an outage or maintenance, wait it out. - Restart and go wired
Restart the PS5, use a LAN cable if you can, then set up the connection again in Settings > Network. - Move closer to the router on Wi-Fi
Bring the PS5 nearer the router and clear anything between them. - Power-cycle the router and modem
Turn them off, wait at least 5 minutes, then turn them back on. Update the router firmware if the maker offers one. - Open Sony's ports
TCP 80, 443, 3478, 3479, 3480 and UDP 3478, 3479, 49152–65535. Your ISP or router maker can help. - Try a static IP or different DNS
In Settings > Network > Settings > Set Up Internet Connection, set the IP manually or enter a public DNS server temporarily. - Try again later
If nothing helps, Sony says the line is probably busy; wait and retry.
