I can’t access OneDrive no matter what I try

Verify that Microsoft 365 Personal and OneDrive are attached to the same Microsoft account; if they are and the subscription is active, this two-year ERR_EMPTY_RESPONSE failure needs Microsoft Support to investigate the account’s OneDrive service rather than more browser troubleshooting.

1. Check the account and subscription state

Since Safari, Chrome Incognito, VPN endpoints, and a hotspot all produce the same result, do not repeat those tests.

1. Sign in to the Microsoft Account dashboard.
   • If sign-in fails here too, use the sign-in assistance offered on that page.
   • Microsoft lists successful dashboard sign-in as the first check for OneDrive access failures.^1^
2. Open Microsoft account Services.
   • Confirm Microsoft 365 Personal shows Active.
   • Note the Microsoft account/email shown there.
3. Open Microsoft storage.
   • Check whether OneDrive reports its normal allowance, Account frozen, or an exceeded quota.
   • An over-quota OneDrive account becomes frozen after three months; the displayed remedy is to reduce storage usage.^2^
4. Ensure the account used in steps 1–3 is exactly the account being sent to OneDrive. A Microsoft 365 subscription can be active under one Microsoft account while OneDrive is being opened under another.^3^

Also check the Microsoft 365 service status. A current outage would explain a temporary failure, but not continuous failure dating from the original purchase.^1^

2. Escalate it as a personal-account technical issue

If the dashboard works, Microsoft 365 Personal is active, storage is not frozen, and the same account is being used, contact Microsoft Support again through the personal-account technical-support route:

1. Open Can't sign in to OneDrive.
2. Under Personal accounts → Technical support, select Contact Microsoft Support.
3. Enter:
   “Personal OneDrive has never opened since Microsoft 365 Personal was purchased. onedrive.live.com consistently returns ERR_EMPTY_RESPONSE.”
4. Include:
   • The screenshot.
   • The approximate subscription purchase date.
   • Confirmation that Microsoft account sign-in succeeds.
   • Confirmation that the subscription is active and storage is not frozen.
   • Confirmation that Safari, Chrome Incognito, VPN endpoints, and a mobile hotspot have already been tested.
5. Ask for investigation of account-level OneDrive access/service activation, not another browser-cache checklist.

Microsoft’s personal-account guidance directs subscription problems to Account & Billing Help and technical OneDrive problems to Contact Microsoft Support.^4^

One remaining isolation test

Only if every test so far used the same computer, try https://onedrive.live.com from a phone or another computer while connected to the phone’s cellular data—not the original Wi-Fi.

• Fails on the second device as well: provide that result to Support; it strongly isolates the issue from the original computer.
• Works on the second device: investigate filtering on the original device, such as firewall, security software, or DNS filtering. Microsoft identifies firewall, VPN configuration, and provider filtering as possible OneDrive access blockers.^1^

Do not post the email address, subscription order number, or other account identifiers in this public thread.
