Microsoft Teams Says There's No Connection - There Is

I have the same issue since yesterday on Windows 10.  Tried everything everyone else suggested and nothing works.  No, I can't even access the online portal.  Edge, Chrome, Opera, Firefox, Brave, all browsers are unable to access the web portal.  

I have had nothing but problems with Teams since we installed it a few months back.  It is obviously a flawed product but my boss always tells me that he expects me to have it running correctly.  He never has problems so it must be me, NOT!

I know that this will fall on deaf ears but PLEASE!  MICROSOFT!  FIX THIS PRODUCT!!!

I have an internet connection on my laptop. I can access my email, web pages, and this site.

However, when I click on Microsoft Teams it says "We couldn't connect to the internet. Try checking your connect."

There is also an error message: 

"desktop-0d71a186-8118-4720-b394-b0098d0c8298

Error code - online_check_failed exceeded retry attempts

Failed to connect to settings endpoint."

I have tried troubleshooting and added Teams to my firewall (per other directions). When I first installed it, it did ask for my logon. I had to get a new one from my office. Now I cannot get back to that page at all.

Any suggestions for getting Teams to start when I clearly have internet access.

hi

Same issue affecting one user here, MacOS.  Came back up after several minutes.

It is not letting me in it says the code conection is wrong

I have tried two seperate computer now and both show same issue - cannot connect to the internet.  This is complete rubbish. Nothing else has an issue connecting...Skype, Zoom, Webex all working OK.  Tried loads of things. Nothing works.
