Workaround

Star Citizen service access is blocked by API-denied Error 403

Tracked since 21 Aug 2026 · Last researched 21 Aug 2026

Problem

The RSI Launcher or game-service connection is blocked by API-denied Error 403. This is the service-access failure, not an HTTP 403 that appears only while downloading game files.

Applies to Alpha 4.9.x LIVE · Current

Best current action

Change the VPN server or region

If you already use a VPN or proxy, switch to a different server or region and retry once. Stop if the same 403 returns.

A different endpoint tests another network route. This is the strongest current action for this state, but no endpoint is known to work consistently.

What to do

  1. Fully close the RSI Launcher.
  2. Reconnect the VPN through a different server or region.
  3. Reopen the launcher and retry the same service connection once.

Any reported benefit is limited to regaining access; it does not establish a universal result.

Other options

Disable the VPN or proxy

Disconnecting the VPN tests the ordinary ISP route. Use this only when a VPN or proxy is active.

Steps

  1. Disconnect the VPN or proxy without changing other settings.
  2. Fully close and reopen the RSI Launcher.
  3. Retry the service connection once.

API-denied 403 can also occur without a VPN, so this does not cover every case.

Close the launcher, wait, and retry once

Use this when the VPN actions do not apply; it costs one clean launcher restart and retry.

What to try

  1. Exit the RSI Launcher completely.
  2. Wait briefly, then reopen it.
  3. Retry once; stop repeating if the same 403 returns.

This remains Unverified for the exact API-denied 403 state.

Flush DNS once

Use this as a one-time local network check after the 403 persists.

What to try

  1. Flush the local DNS cache using the operating system's normal network tools.
  2. Retry the same connection once.
  3. Stop treating it as relevant if the 403 persists.

Mixed outcomes do not support repeated DNS attempts.
