These issues started when I switched to a new ISP. Microsoft Teams and Minecraft marketplace and character were not functioning unless I got off the WiFi or enabled a VPN. After a bit of troubleshooting, I discovered that the issue was caused by the "IPv6 Router Advertisement" being enabled on the router provided by the ISP. When enabled, devices running Android and Chromebook default to using IPv6 but for some reason fail to reach sites like Microsoft's login "login.microsoftonline.com".
The fix was to DISABLE "IPv6 Router Advertisement" in the router.
If you don't know how to do that, you could contact your ISP. Alternatively, you could try to find your router manual if you're comfortable with accessing the admin interface and know where to find credentials.
To establish whether this is your issue, try the following:
Enable a VPN (free one ProtonVPN) and restart Minecraft. If everything works, your wifi/router/internet could be the culprit.
If you are on a mobile phone, go off wifi and restart Minecraft. If everything works, your wifi/router/internet could be the culprit.
Use the command line to test connectivity. For Android/Chromebook, you will need to install Termux from the Play Store and then run the command pkg install inetutils to install the network utility telnet. Now check the connection by running "telnet login.microsoftonline.com 443" If you see something like the one below, then you potentially have that issue
~ $ telnet login.microsoftonline.com 443 Trying 2603:1027:1:d8::5... Connection failed: Network is unreachable Trying 2603:1026:3000:d0::6... Connection failed: Network is unreachable Trying 40.126.32.74... Connected to login.microsoftonline.com. Escape character is '^]'.
