Issue with the BRAND_CONTENT_URL
I have customized the Agent window login for Adding the our own Image left side of the Window. I have added one image in CP assets folder. I am able to see the Image when I try to login into my console and there were no issues. But, My Agents are located in US and when they try to access Agent window, it is throwing an error. they are getting an error message after they click on the "log in" button. "unsupported image format" and then "script error, an error has occurred..." If I remove that URL, the login functionality is working.
