How to Troubleshoot Intermittent SharePoint ERR_FAILED Errors

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Accessing SharePoint sites, lists, and files during daily operations.
Observed behavior: Pages and resources intermittently fail to load, displaying an ERR_FAILED error message to multiple users including administrators.

Before you start

Before escalating the issue, gather specific details such as the exact timestamps of the errors, affected URLs, user accounts involved, and the web browsers being used.

Solution 1Recommended

Contact Microsoft Technical Support for Tenant Diagnostics

Since the ERR_FAILED issue affects multiple users and involves backend tenant routing, administrators must escalate it to Microsoft Support for investigation.

Community moderators and standard troubleshooting guides cannot resolve backend tenant data issues. Because this failure happens intermittently across different files and affects multiple users, it requires network and tenant-level diagnostics that only Microsoft engineers can perform.

Log in to the admin center

Navigate to the Microsoft 365 admin center and log in using your administrator credentials.

Create a support request

Go to the 'Support' section on the left-hand menu and select 'Help & support' or 'New service request'.

Describe the issue

Explain that multiple users are experiencing intermittent ERR_FAILED errors across SharePoint pages, lists, and files.

Provide diagnostic data

Attach all gathered data, including timestamps, affected URLs, user details, browser network logs (such as HAR files), and relevant tenant logs.

Contact Microsoft Technical Support for Tenant Diagnostics

Administrative privileges required: You must have administrative rights in the Microsoft 365 tenant to access the support portal and submit diagnostic logs.

Frequently Asked Questions

Why am I getting an ERR_FAILED message in SharePoint?

The ERR_FAILED message typically indicates a network connectivity issue, a browser caching problem, or a backend tenant failure on Microsoft's servers that prevents the requested page or file from loading.

Can a standard user fix the SharePoint ERR_FAILED error?

If the issue intermittently affects multiple users across an organization, a standard user cannot fix it. It requires an IT administrator to gather tenant network logs and directly contact Microsoft Technical Support.

What information should I provide to Microsoft Support?

You should provide exact timestamps of the failures, the specific SharePoint URLs affected, the email addresses of the users experiencing the issue, and the web browsers being used, along with any HAR network logs.
