ns_error_net_interrupt in firefox but not in chrome

I have a website deployed in AWS but whenever I use firefox to access my website and make a request, it always blocked the request and throws an error "ns_error_net_interrupt" But when I access my website in chrome, everything is working fine. Is there anyone who has idea of what's going on? error

Solution

  • It looks like Firefox has a bug in the http3 handler with some xhr requests. If you're in AWS and using CloudFront you probably have the default http1.1, http2, and http3 protocols. I disabled http3 and Firefox requests started working again.

    More information:

    there is no bug reported, but searching the source code for that error i find comments like this

    case PR_END_OF_FILE_ERROR:  // XXX document this correlation
  rv = NS_ERROR_NET_INTERRUPT;

    and this

     if ((NS_ERROR_NET_INTERRUPT == aError || NS_ERROR_NET_RESET == aError) &&
  SchemeIsHTTPS(aURI)) {
// Maybe TLS intolerant. Treat this as an SSL error.
error = "nssFailure2";

    }
