Issue Regarding Meeting SDK

Getting Issue while joining meet via Meeting SDK :

I created a Zoom app and used its credentials to create a Zoom meeting and generate the Meeting SDK signature. However, when I try to join the meeting, I receive an “Invalid Signature” error.

I have thoroughly reviewed both the official Zoom documentation and the Meeting SDK sample repository, and my implementation matches the recommended approach. To verify my code, I created a new Zoom app using the same implementation, and it worked correctly initially.

However, after some days, the newly created app also started returning the same “Invalid Signature” error without any changes to the implementation.

Could you please help me understand what might be causing this issue? I have attached screenshots for reference.
