Meeting SDK for Web v3.12 **Description** I am using the JavaScript Meeting SDK for Web. I have successfully (I believe) implemented a JWT auth endpoint as I receive a signature that verifies at the jwt. io website. I have created my API app and provided the Client ID as the sdkKey in the JavaScript client-view.js configuration, along with the auth endpoint, meetingNumber, password, role and userName. I am unable to join the meeting. I appreciate any assistance! **Error** Joining Meeting Timeout or Browser restriction Fail to join the meeting. Invalid sdkkey. **Troubleshooting Routes** I have tried changing configuration settings in my API app, however I’m not 100% sure what I’m doing. ---

Hi @ScottL we do, however there are many threads with this topic with solutions. Have you down a search on the forum? There are a number of potential root causes.

I found a few threads on this topic but the ones I found were all closed after 30 days with no resolution. Maybe I didn’t search thoroughly enough but after the first few dead ends I thought posting my issue would get to a resolution more quickly. Thank you for the links, the bottom two helped me solve my issue. I did not have all of the required fields in my JWT payload and I had mistakenly set the iat (“valid from”) timestamp to be the same as the exp (“valid until”) timestamp, so the token was was invalid because it was being created with a “valid from” timestamp in the future. Much appreciated Gianni! ---

Perfect, I’m glad the resources helped identify the root cause and you were able to share back here.
