Using angular and the web sdk, and the c# code from the zoom documentation to generate a signature, located here:

I am able to join any zoom meeting. However, if i want to host a meeting using the same code, but i change the join flag from a 0 to a 1 to host the meeting, i get an error:  
“Joining meeting timeout”  
“Signature is invalid.”

If I change that join flag back to a 0, I am able to join any meeting again, which makes me think my signature is fine? However, i am not sure what i am doing wrong to host a meeting via the Web SDK.

Any help would be appreciated!

Hey @marshallp,

Happy to help! 🙂 Make sure that the meeting you are trying to start, is under the same account as the JWT App you are using to generate the signature.

If you are still having issues, please share your Web SDK signature for a test meeting here so I can debug it for you.

Thanks,  
Tommy
