How to authorize Teams to connect to Smartsheets

I am trying to connect Teams to Smartsheets. I have installed the app within teams and the bot is prompting me to allow access and displays an Allow Access button. When I click it, it takes me to a browser window that prompts me to deny or allow. When I click Allow, I receive an error indicating that the Authentication request has expired.

Has anyone else experienced this? How did you fix it?
