Allowed origins: your current tenant URL (e.g., <A href="https://company.us.qlikcloud.com" target="_blank">https://company.us.qlikcloud.com</A>).</LI><LI>Go to Settings &gt; Sharing and reports &gt; Qlik add-ins for Microsoft Office. Select the new OAuth client from the dropdown and download the updated manifest.xml file.</LI><LI>Distribute the new manifest.xml to your users. Users must remove the old add-in from Excel before installing the new one.</LI></OL><P class="">Important: If users access the tenant through both the original URL and an alias, add both to the allowed origins field. Missing either one will cause authentication to fail.</P><P>&nbsp;</P><P><STRONG><FONT color="#339966">Cause</FONT></STRONG></P><P>The Excel Add-in manifest.xml and its OAuth client are created as a pair and are tied to a specific tenant hostname. When the tenant is renamed, the existing OAuth client retains the old hostname in its redirect URIs and allowed origins, triggering OAUTH-1. If the manifest is recreated but the OAuth client configuration still has incorrect settings, OAUTH-14 follows. The manifest file cannot be edited to point to a new hostname. It must be regenerated from a newly created OAuth client on the correct tenant.</P><P>&nbsp;</P><P><FONT color="#339966"><STRONG>Related Content</STRONG></FONT></P><UL><LI>Tabular Reporting OAUTH Error Status 400 resolution:&nbsp;<A href="https://community.qlik.com/t5/Official-Support-Articles/Tabular-Reporting-OAUTH-Error-Status-400-resolution/ta-p/1716773" target="_blank">https://community.qlik.com/t5/Official-Support-Articles/Tabular-Reporting-OAUTH-Error-Status-400-resolution/ta-p/1716773</A></LI><LI>Qlik Help: Administer the Qlik add-in for Microsoft Office:&nbsp;<A href="https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/Admin/mc-administer-add-in.htm" target="_blank">https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/Admin/mc-administer-add-in.htm</A></LI></UL> Tue, 10 Mar 2026 16:31:06 GMT AnaSilva 2026-03-10T16:31:06Z https://community.qlik.com/t5/Member-Articles/Qlik-Excel-Add-in-OAuth-Errors-After-Tenant-Rename-OAUTH-1-and/ta-p/2544483 <P>Resolve OAUTH-1 and OAUTH-14 errors on the Qlik Excel Add-in caused by a Qlik Cloud tenant hostname rename.
