Often the cause for this error message cropping up is the result of an antivirus or firewall interfering with Elite Dangerous's secure connection.
The best way to ensure that this is not the case is to disable your antivirus/firewall program temporarily.
Please be aware that once disabled most antivirus programs still require that you restart your PC for them to fully turn off.
While your antivirus/firewall is disabled, start Elite Dangerous and proceed to the main menu. You should no longer be presented with this error message.
If you'd like to re-enable your anti-virus program, please check the following options:
- Kaspersky Internet Security - Untick Always scan encrypted connections
- ESET NOD32 - Disable Web Access Protection
- Avast - Disable HTTPS Scanning
You must restart your computer to apply these changes.
In some cases, you may need to resynchronise your system clock as shown here.
