Can’t connect to Microsoft Teams

I have a new computer that periodically fails to connect to Microsoft Teams. When this happens I am also unable to connect via Outlook. As a temporary fix. I restart the computer and I am able to connect to Teams and Outlook, but only for a few days.
I have reinstalled Office 365 and fully cleaned the system registry, but with the same results.
Please advise.
Thank You,
