Star Citizen service access is blocked by API-denied Error 403
Tracked since 21 Aug 2026 · Last researched 29 Aug 2026
Problem
Access to the RSI Launcher or another Star Citizen service is blocked by an API error, sometimes shown as Error 403 or API Denied Request. CIG still lists this as an active Alpha 4.10.x issue.
Applies to Alpha 4.10.x LIVE · Current
Current conclusion
No universal fix is confirmed
If the denied connection is already using a VPN, turn it off and retry once. If the same error remains, switching that VPN to another server is a fallback. CIG has not published a supported recovery step for players who are not already using a VPN.
If the denied connection is already using a VPN
Turn off the VPN and retry once
CIG says some VPN users regain access after turning the VPN off, but it also warns that this does not work for everyone.
What to do
- Turn off the VPN currently carrying the RSI Launcher or service connection.
- Retry the same connection once without the VPN.
This applies only when the failed connection is already going through a VPN.
Diagnostic checks
These checks can identify the affected state, but they are not fixes.
Report the persistent denial to LCH-2629
If the applicable VPN steps fail, CIG asks for the steps you tried and whether any of them helped. The report supports the investigation; it will not restore access immediately.
What to check
- Open Issue Council report LCH-2629.
- Add the troubleshooting steps that failed or worked and your ISP name only if you are comfortable sharing it.
Use this after the steps that apply to you have failed, or when you have useful results to add.
Other options
Switch the VPN to another server
If a VPN is already active and an off-VPN retry is unavailable or returns the same denial
CIG also lists a different VPN server as a possible route. Older players reported both success and failure, so no server or region can be treated as reliable.
Steps
- Switch the active VPN to a different server or region.
- Retry the same connection once through the new endpoint.
Keep this as a fallback when you already use a VPN and an off-VPN retry is unavailable or returns the same denial.
What's not worth trying
Do not treat waiting as the fix
Waiting may leave you blocked for hours or days. It was suggested during an older Alpha 4.8 load spike, but one clean retry is enough; repeated waiting is not current Alpha 4.10.x recovery guidance for this error.
Do not rely on a DNS flush
A DNS flush may make no difference, and CIG does not currently list it for API-denied Error 403. The older outcomes conflict, so do not treat it as a current fix.
Do not start a new VPN just for this error
Starting a new VPN may still leave the same error. CIG's current advice applies only when the failed connection already uses a VPN.
Do not reinstall the launcher for this denial
Reinstalling can consume time and bandwidth and may still leave the same denial. CIG does not currently recommend it for this service-access error.
Boundaries and evidence
Use this page when the launcher or an RSI service connection itself is denied. An HTTP 403 that appears only while game files are downloading is a different failure.
CIG says turning off or switching an active VPN helps some players, not everyone, and gives no success rate.
No independent Alpha 4.10.x result was available for either current VPN step.
CIG has not published a supported recovery step for this error when no VPN is already active.
Older player results may reflect patch-day load or a backend recovery rather than the step taken.
