The error "AuthSdkError: The JWT was issued in the future" occurs when the authentication server detects that your login token's issue time appears to be in the future. This typically indicates a time synchronization mismatch between your device and Acoustic's authentication servers.
What causes this error
- Your device's system clock is set ahead of the correct time
- VPN or proxy connections causing time synchronization issues
- Browser cache storing outdated or corrupted authentication data
- Using an incorrect or unsupported login URL
How to fix it
Step 1: Verify your system clock
Ensure your device's date, time, and timezone are correct. Enable automatic time synchronization or sync with a network time server if needed.
Step 2: Disable VPN or proxy
Disconnect from any VPN or proxy services, as they can interfere with time synchronization. Then try logging in again.
Step 3: Clear browser cache and cookies
Clear cached data, cookies, and stored site data related to Acoustic to remove any invalid authentication tokens stored in your browser.
Step 4: Use the correct login URL
Always log in using the official Acoustic login page: https://login.goacoustic.com
Step 5: Try a different browser or incognito mode
Use a private or incognito window, or switch to a different browser, to rule out browser-specific issues or extensions interfering with authentication.
Step 6: Check your internet connection
Ensure you have a stable connection without corporate proxies. If possible, try using a mobile hotspot to rule out network-level interference.
Step 7: Wait and retry
In some cases, waiting a few minutes and retrying the login resolves temporary synchronization issues.

Prevention tip: Keep your device's system time regularly synchronized with a network time server to prevent future authentication-related errors.
