MY FIX!! MS TEAMS says I'm offline when I'm connected to my network with no issues

My Teams on my laptop kept telling me I was "offline" even though I was connected with a strong signal to my wi-fi, I could browse the web with no issues, connected to VPN and (through VPN), I was RDP'd into servers for work.

This was VERY frustrating as I had meetings to attend and I didn't want to do it on my phone. Plus not being able to communicate (messaging) over Teams.

I tried SO many things:

Logged out of Teams and logged back in
Restarted Microsoft services I saw in services.msc
Uninstalled/reinstalled Teams
Disconnected and reconnected from my wi-fi
I had recently changed my password so I cleared out my Microsoft credentials saved in my Credentials manager just to be safe
Another reboot

Know what FINALLY fixed it? Allowing the app in my Windows firewall...

**BEFORE YOU READ THE REST, I wanted to share a fix that worked for another person (they commented below) - thank you biradarvenkat **

To resolve this issue, go to Control Panel > Internet Options > Connections > LAN Settings > ensure Automatically detect settings option is checked.

Another comment with a fix that worked for IanJCI (thanks for sharing!!)

Non of the other Fixes worked, but I disconnected from our corporate network, and connected using a new Internet connection not connected to our network. This changed my status to Online, and it has remained online when reconnecting to the corporate LAN

As an Update, Every time I start the computer, Teams shows me offline and I have to unplug the LAN cable, change Internet connection for it to show me as available, then I change back to corporate LAN, and it stays showing available most of the day.

If that didn't work for you - please try the steps below 🙂

I already saw a "teams.exe" app in the list of programs and made sure all instances were checked to be allowed through Public & Private but I figured I would navigate directly to the location that my Teams program had in it's properties

So I right-clicked my Teams icon in my taskbar, when the window popped up, I selected Properties. I saw that it had the Target as:
C:\Users\My Username\AppData\Local\Microsoft\Teams\Update.exe

In the Windows Firewall settings, I selected the option to Allow an app or feature through Windows Firewall

I selected the button at the bottom to Allow another app...

The "Add an app" window appeared --> I selected the Browse... button next to the "Path" field

In the Browse window, I navigated to the location that I grabbed from the TEAMS properties window earlier:
C:\Users\My Username\AppData\Local\Microsoft\Teams

Once I was in that folder, I double-clicked the Update.exe application and it appeared in my "Add an app" window as "Microsoft Teams" (of course!)

I pressed the Add button at the bottom. After that, I was magically able to log into Teams with no issues!!! OMG what a relief!

I am hoping to save someone else the headache I had figuring this out lol, it was a fun one!
