Hi @Lars svantesson, @kirbster 1,
Welcome to Microsoft Q&A forum.
Based on the error codes you provided, 715-123130 typically indicates a temporary server-side block or throttling from the Microsoft backend. This issue can happen due to some causes, such as IP reputation, account status, or high server demand, and requires troubleshooting to identify the specific trigger.
Therefore, I suggest you try these three troubleshooting steps:
- Use an InPrivate or Incognito Window:
- Open your browser in private mode and sign in to the Windows Insider ISO download page again.
- This bypasses any cached tokens or corrupted cookies that might be causing the server to reject your request.
- Switch Your Network Connection: If you are currently using a VPN or a proxy service, please disable it and try a direct connection. If the issue persists, try connecting to a different network, such as a mobile hotspot, to rule out an IP-based restriction.
- The 24-Hour Reset: Many backend throttles are automated and temporary. If the previous steps do not work, please wait a full 24 hours before making another download attempt to allow the server-side cooldown to expire.
Kindly update the outcome to let me further check if the problem persists. I am here to assist you until we get this resolved.
