I get this message when I try submitting a receipt for reimbursement

Question

I am trying to submit a bill for reimbursement for my medication to my company. I keep getting the following error message. ERROR HTTP Status 0-unknown error

Answer 1

Hi Elizabeth Linnell,

I'm sorry to hear that you're blocked by a vague error while trying to submit a reimbursement. This “HTTP Status 0 – unknown error” usually means the website failed to communicate with the server. The failure happens before the request is processed.

The Q&A Assist already covered the general browser‑side checks, I'm wondering if you had time to check them out yet? If none of that helps, the issue is with the company reimbursement system or its connection, and not something Windows can fix.

• You’ll need to contact:
  • Your company’s HR / Finance team
  • Or the support contact for the reimbursement portal
• Ask them to check Server logs, Account permissions, File upload limits or portal outages...

In short, this error likely cannot be fixed from Windows or Microsoft. It requires action from the organization or service that runs the reimbursement system. You’re doing the right thing looking for help, it just needs to be handled on their side.

Answer 2

The error message indicates that the site where the receipt is being submitted is failing before it can return a normal HTTP status code. This is a site/platform issue rather than a problem with the receipt itself.

Try the following steps in order:

1. Refresh and retry
   • Reload the page and try submitting again.
   • If possible, sign out of the site, sign back in, and retry.
2. Try a different browser or device
   • Use another browser (for example, switch between Edge, Chrome, or Firefox).
   • If using a mobile browser, try from a desktop browser, or vice versa.
3. Clear cached data for that site
   • Clear cookies and cache for the reimbursement portal’s site only, then sign in again and retry the submission.
4. Check whether the service is running
   • If this is an internal company portal, check with the internal IT/help desk to see if there is a known outage or maintenance.
5. Capture the full error details
   • Take a screenshot of the error and note the time and any correlation or error codes shown on the page.
   • Provide these details to the company’s IT support or the support contact for the reimbursement system so they can investigate server-side issues.

If the reimbursement portal is part of a larger system (for example, Microsoft Dynamics AX or another expense system) and the error persists across browsers and devices, only the system administrator or vendor support can resolve the underlying server or configuration problem.
