ssl - nginx error message - what does "peer" refer to? -


To debug a nginx error issue, I must first understand the error log message. Our NGX periodically writes special error log messages.

Log message

" Peer-off connection to SSL handshake (104: connection reset by peer) while SSL upstream ".

What does "peer" mean?

I should know: Does "peer" reflect upstream, which means that upstream has closed the connection during the SSL handshake, or does it refer to the customer , Which means that the client closed the connection while load balancer and webserver were internally done during a handshake?

  • SSL provider: commodo

    setup

    • nginx load balancer
    • 2 The webserver (upstream) is running IIS8

    • P

    in this case shows upstream only So if we take that co-worker, then it will mean that two SSL handshakes (client-> NGN, NGN-> upstream) are simultaneously, which is not understood - to establish a connection to the customer and send a query , And only nginx

    Designed for joining choose upstream
