Size of Headers Too Long Error

[Andrew Bishop1]

Has anyone else received this error message about size of headers being too long?

The User is able to access ServiceNow on Internet Explorer, but not on Chrome and/or the desktop application.

Hi Andrew,

Can you try clearing the cookies for IE. As, sometimes the website doesn't allow browser cookies over a certain size, or cookies stored in your browser might be corrupted.

Thanks,

ONLY in Chrome I have to clear browsing data to fix it.

Wrench > Tools > Clear Browsing Data

Check the following:

• Clear browsing history
• Clear download history
• Empty the cache
• Delete cookies and other site data

Then click "Clear Browsing Data" button and refresh your page.

Can you confirm the issue is with the ServiceNow URL and not an SSO/ADFS URL? Sometimes those redirect links are very long and could cause that message. To validate, use https://[instance].service-now.com/navpage.do page to access SNOW without using AD authentication.
