Troubleshooting the Data Server

This section provides solutions to the errors you might experience while working with Flexmonster Data Server. If you cannot find your error here or you are facing any issues with Flexmonster Admin Panel, contact our technical support.

Browser error: ‘ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY’

The main reason for this error is that HTTP/2 does not support the Data Server’s SSL certificate. See this thread to learn more.

One of the possible solutions to this error is to set the protocol to HTTP/1.1 in flexmonster-config.json:

"HTTPS": {
    "Enabled": true,
    "Protocols": "Http1",
    "Certificate": {
        // your certificate
    }
}
