Hi @Ganesan_IDC

Work through these articles and see if it resolves

As your internet is working fine, it sounds like Local Firewall/AV is likely causing the issue. If they don't resolve raise them to IT. If that doesn't resolve open a ticket with Microsoft who will request the logs so they can isolate the issue

Hi Christopher Hoard,

Thanks for your reply. Your points almost solve my issues. After that i research the issue. Finally I Found one solution for this issue. 

I trying to connect the team with my mobile hotspot. After that its working fine. So problem cause my org firewall blocking the teams. 

I read the article about teams ip exception information document. 

https://docs.microsoft.com/en-us/microsoftteams/prepare-network 

Based on this document i configure my firewall. 

After that its working fine. 

Note: 

Someone referred the fiddler tool. Its really working nice. This tool find out the what are ports blocked in my computer network. 

Thanks for your help. 

Have a good day.
