    Cannot Login to backoffice Umbraco 8.1.3

    I am trying to login to backoffice in Firefox browser and it fails, other browsers are fine.

    I got this error on the console:

    No url found for api name updateCheckApiBaseUrl

    enter image description here

    the Umbraco version is 8.1.3 and Firefox version is 71.0

    I tried to clear the history and cookies but the same issue still appears.

    Note that one my clients faced this issue on Safari as well.

    Hi Saif,

    I had the same problem in 8.5.1. on Chrome 79. I fixed it by deleting my browser cache and refreshing the login page. Hope this helps you too.

    Hi Saif,

    I also encountered this problem. I upgraded from 7.15.7 to 8.18.3. Have you solved this problem?

    Thanks & Regards,
