Site Not Secure

edited 05/13/24 in Smartsheet Basics

When I go to, I get an error that….. is not secure. In the browser window, it lists "Pretty Print [] and then another line below that includes -

{"code":"UM117","details":null,:"message":"Access token expected in the X-Authorization header"}. It does this under two Windows profiles on the same computer. Cleared cache and cookies. Has issues with Chrome, Edge and Firefox. Tested on someone else's system and it works. System scans clean of malware / viruses and SFC indicates no Windows corruption. Would you have any ideas on how to resolve the issue?
