I'm unable to join Teams meeting in the Teams web app that is created by a user from their Teams Mac Client.

@Haseeb Elahi ,

Does this issue persist all the time? Or what changes do you do before this issue happened?

Does anyone else have the same issue?

Could you login Teams web client properly?

You could check if you enable the URLs for Teams in the browser as below:

1. In the Edge Settings window, select Site permissions and Cookies and site data.
2. Turn on Allow sites to save and read cookie data (recommended) and make sure Block third-party cookies is turned off. Alternatively, follow step 3 if you need to keep third-party cookies blocked.
3. In the same window, under Allow, select Add to add the following sites
   • [*.]microsoft.com
   • [*.]microsoftonline.com
   • [*.]teams.skype.com
   • [*.]teams.microsoft.com
   • [*.]sfbassets.com
   • [*.]skypeforbusiness.com

Besides, check if UDP 3478-3481 ports and TCP 443, 80 ports are opened in firewall. For more information, please refer to this link: https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide#skype-for-business-online-and-microsoft-teams.
