Hi Robin Brookes,
Welcome to the Microsoft Q&A forum.
The error code 0x8015DBFE usually points to a local sign‑in or connection setting on the device rather than an issue with the game itself.
Here are some possible troubleshooting steps that you can consider in this situation:
1, Sign out and refresh account access
- Sign out of the Xbox app.
- Visit Microsoft Account > Devices and remove this PC.
- Go to Xbox Account, ensure to check for age verification on your account.
- Restart the device, then sign back into the Xbox app and open Solitaire.
2, Disable network filters temporarily
- Turn off any VPN, proxy, or third‑party firewall software.
- Restart Windows and test Solitaire again.
3, Test with a new Windows user profile
- Go to Settings > Accounts > Other users and create a temporary local user.
- Sign in to that account, install Microsoft Solitaire Collection, and try signing in.
If the issue continues after these steps, all local troubleshooting has been completed. The fastest next step is to directly contact Microsoft Support.
