Prominence Poker Authentication Error | Guide to Fix

January 16, 2026 Kroger Error Fix 0

This error is often caused by a “handshake” failure between your local client and the Prominence Poker servers, rather than a total server outage.

Here are the confirmed fixes for January 2026, broken down by platform.

Quickest Fix (All Platforms)

Try a Different Network Temporarily: The most consistent workaround for the “Authentication Failed” loop is to force the game to see a new connection path.

  1. Disconnect your PC/Console from your home Wi-Fi/Ethernet.

  2. Connect it to a Mobile Hotspot (from your phone).

  3. Launch the game and log in.

  4. Once you successfully reach the lobby, you can often switch back to your normal internet connection.

PC / Steam Fixes

If you are on Steam, the issue is usually cached network credentials. Do not just reinstall; it rarely fixes this specific error.

Method 1: The “Flush” Command (Most Success)

  1. Close Prominence Poker and Steam completely.

  2. Open your Command Prompt as Administrator (Search “cmd” in Windows start menu -> Right Click -> Run as Admin).

  3. Type the following commands one by one, hitting Enter after each:

    • ipconfig /flushdns

    • ipconfig /release

    • ipconfig /renew

    • netsh winsock reset

  4. Restart your computer and try launching the game.

Method 2: Verify Integrity

  1. Right-click Prominence Poker in your Steam Library.

  2. Select Properties > Installed Files.

  3. Click Verify integrity of game files.

PlayStation (PS4/PS5) Fixes

On PlayStation, this error frequently happens because the license “token” on your console is out of sync with the server.

Fix: Restore Licenses

  1. Go to Settings > Users and Accounts.

  2. Select Other.

  3. Choose Restore Licenses.

  4. Wait for the process to finish, then restart the console and launch the game.

Note: Also ensure your console’s Date and Time are set to “Set Automatically via Internet.” A time mismatch can instantly cause an auth failure.

Xbox Fixes

Xbox users often encounter this due to the “Instant-On” feature keeping a stale session active.

Fix: Full Power Cycle

  1. Hold the power button on the front of the Xbox for 10 seconds until it turns off completely.

  2. Unplug the power cord from the back for 30 seconds (this clears the cache).

  3. Plug it back in and turn it on.

Is the Server Down?

If none of the above works, the servers might actually be down for maintenance.
