Error: The page you are looking for doesn't exist or Page not found

Issue symptoms

I cannot access my Zendesk instance. I see the error message: This page doesn't exist, or Oops The page you are looking for doesn't exist or Page not found when I access my Zendesk account.

When I visit my account, for example: https://mysubdomain.zendesk.com, it redirects automatically to https://mysubdomain.zendesk.com/hc.

Resolution steps

There are multiple causes for this This page doesn't exist error:

Verify your current plan and ensure your help center is available

If you recently changed your Zendesk plan, the help center can be disabled. Activate your help center again

Note: You must be a Zendesk admin to activate the help center. Guide admins who are not Support admins cannot enable the help center.

If you do not have an active help center, the page is not visible to customers when they visit the URL

If none of the options apply and you still see that error, try to log in to https://yoursubdomain.zendesk.com/agent, replacing yoursubdomain with your actual subdomain.

From that page, if this error appears: The page you are looking for doesn't exist or Page not found, collect a HAR file and evaluate your traffic. You can face network issues, or a VPN or firewall might block your connection and lead to a timeout. This returns a 404 response in your HAR file and hash values show after your URL:
