We meet an issue when scanning our website. Arachni returns this message

Giving up trying to audit:
[2013-10-06 07:53:32 +0200] Couldn't get a response after 5 tries

http request limit parameter is set to 20. could you tell me why it stops at 5 time?

    The http-req-limit parameter has to do with concurrency so it doesn't affect this situation.
    The error message is pretty self explanatory though, Arachni tried to retrieve a page in order to audit it but the server didn't respond, Arachni retried 4 more times just to be safe, but the server returned nothing.

    It could be that the server was overwhelmed by the scan and had trouble managing the workload or flat out died.

    Actually, messing with http-req-limit could help because by reducing concurrency you may be able to keep the server more responsive. What I recommend is setting it to 10 or so and see if that makes any difference.

    First, thanks for your answer.
    About your first answer, I tried to scan my website and I don't think that server was overwhelmed. Nevermind...

    Moreover, "http-req-limit" was set to 20, so according to your second answer, isn't it?

    Kind regards,

    If the server wasn't overwhelmed then is there a chance that your IP was blocked by a firewall or something?

    It could be this. I don't know network design of our webhoster.

    I will try to get this information and get outbound traffic report, if some security device of our webhoster block my IP adress from scanning.

    Thanks and regards,
