Update dialog not showing | Connection terminated during handshake

My app is live with the version 2.1.5, and my current installed app version is 2.1.4 but it doesn't showing update alert.
I'm getting this error HandshakeException: Connection terminated during handshake

Here are my upgrader logs:

@chayanforyou Does the lookup URL work for you in a browser? Does your app have permission to request that URL? Are there any other details you can provide that may help us help you?

Lookup URL only working on Chrome browser, But it's not working on Firefox even Postman

@chayanforyou If you need help to resolve this issue, you may need to provide more details about your app, what environment it is running in, the upgrader log, and logcat log, and anything else you think might be helpful.
