HTTPS connections timeout/fail with exception

[Marenz]

Very suddenly, my HTTPS connections start to fail. I was using the dummy certificate at first provided in the https example, but I also generated my own for another instance, but both show the same problem. One is vibe 29, the other the latest.

Here is what the log shows:

Here is the code that sets up the HTTPS:

    auto https_router = new URLRouter;

    with(https_router)
    {
        any("*", &allowAllOrigins);
        match(HTTPMethod.OPTIONS, "/*", &handleOptions);
        // now any request is matched and checked for authentication:
        any("*", performBasicAuth("Site Realm", toDelegate(&checkPassword)));

        get("/green", &managers.matchmaking.getGreen);
        get("/red", &managers.matchmaking.getRed);
        get("/live", &managers.matchmaking.getLive);
    }

    auto https_settings = new HTTPServerSettings;

    with (https_settings)
    {
        port = config.monitor_port;
        bindAddresses = [config.listen_addr];
        tlsContext = createTLSContext(TLSContextKind.server);
        tlsContext.useCertificateChainFile(config.server_cert);
        tlsContext.usePrivateKeyFile(config.server_key);
    }

    listenHTTP(https_settings, https_router);

Sorry for the late reply, I just noticed this now. The call trace above looks like the connection is actually just an unencrypted HTTP connection, just the Libevent2TCPConnection wrapped in a LimitedInputStream. However, the setup sequence looks unsuspicious. Is there any chance that the code below does not belong to the setup sequence below?

This is some time ago now. But I suspect what happened was that I called the https connection with a http:// prefix in the browser (happens easily when you use non-std ports).

Maybe it would be good to have some dumb check in the HTTPS part to see if it is normal HTTP and give a better error message?
