WEBSDK - sudden problem with signature

[ale.g (Uplink)]

---

Description
I have a simple page that has Zoom Web SDK built into it. Created last Saturday and it worked perfectly, tested again yesterday and it worked perfectly. Tried today and it doesn’t work: the message “Signature is invalid” always comes out. I tried updating sdkSecret, changing the version (from 2.8 to 2.9), trying to generate the signature with php, trying to download the demo by changing only sdkKey and sdkSecret but the result is always the same. What can it depend on?

Browser Console Error
{method: ‘join’, status: false, result: ‘Invalid signature.’, errorMessage: ‘La firma non è valida.’, errorCode: 3712}

Which Web Meeting SDK version?
2.9.0

To Reproduce(If applicable)
Steps to reproduce the behavior:

1. Go to LikeEvent
2. See error

Troubleshooting Routes

• change sdkSecret
• update sdk version
• try with other language
• try with sample web sdk app

• OS: [macOS 11.3]
