- Trustwave MailMarshal (SEG) 10.X
- Windows Server 2012 R2
- Management Console website
Symptoms:
- Cannot connect to the Management Console website
- Chrome error: ERR_CONNECTION_RESET
- Firefox error: PR_CONNET_RESET_ERROR
Causes:
- TLS 1.1 and 1.2 for HTTPS is not enabled by default on Windows Server 2012 R2 as originally released. Current browsers require TLS versions above 1.0.
Resolution:
To resolve this issue, ensure that the Array Manager/Management Console server is up to date with Windows Updates.
On a server that is up to date, no further change is required.
- Registry edits to enable TLS 1.1 and 1.2 will not fix this issue.
- Registry changes are not required when Windows Updates have been applied.
