> [@yashkalra088](#): > > Also if you use same user account in another laptop it is working fine. Hi @yashkalra088 , this part makes me wonder if there a server clock drift affecting the signature. Please check out [this article](https://developers.zoom.us/blog/troubleshooting-meeting-sdk-signature-validation/#timestamps-and-expired-tokens) for more info about this Here’s a forum convo about this as well with some sample code: > [@Sporadic Joining Meeting Timeout - Fail to Join Meeting - No Error Detail - Error Callback not Called](https://devforum.zoom.us/t/sporadic-joining-meeting-timeout-fail-to-join-meeting-no-error-detail-error-callback-not-called/93507/12): > > to modify “iat” is important - if the clock on your server is not identical to the clock on the zoom server(s) here is the working example implementation (in JavaScript) iat = currentTime - 30 sec exp = iat + 2 h tokenExp = iat + 2h ---

Hi @gianni.zoom , Thanks you so much for reply, I am making the token at the client browser side not on the server. Also I have tried deducting more than 30 seconds in the code. The signature was invalid(Zoom error) and Also in the signature if you see iat time it is exactly perfect when I have used epoch converter on iat the time and seconds was perfect. ---

Hi @yashkalra088 , Please collect MSDK logs from both laptops (instructions [here](https://developers.zoom.us/blog/msdk-log-retrieval-instructions/))and share in the private message I’m about to start with you. Please also include the following: - MSDK key or MSDK client id [(whichever is available in your MSDK to create JWT)](https://developers.zoom.us/docs/meeting-sdk/auth/#generate-a-meeting-sdk-jwt) - developer email associated with the app and where you will be contacted - failed user signature example - working signature user example ---

Hi @yashkalra088 , Have any of the other search options from the forum helped? - [Zoom Web SDK v2.7.0 "Signature is Invalid" error code 3712 - #3 by j.schoenemeyer](https://devforum.zoom.us/t/zoom-web-sdk-v2-7-0-signature-is-invalid-error-code-3712/75782/3) - [Signature is invalid.', errorCode: 3712 - #4 by chunsiong.zoom](https://devforum.zoom.us/t/signature-is-invalid-errorcode-3712/98826/4) Additionally, can you please clarify if you’re using client or component view and able to reproduce with the sample app? > **[Zoom Meeting SDK for web](https://developers.zoom.us/docs/meeting-sdk/web/)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. ---

Hi, If anyone is facing this issue please make sure that you are making your token at the server. Also your users timezone should be aligned with the token’s timezone(like their computers timezone will also impact so make sure that this is also correct) that is what i have found and fixed the issue. ---
