Mailman 3 SSLError: The read operation timed out - devpi-dev

31 Oct 2013


      So we've been running devpi internall for a few weeks, 1.1 and now 1.2.  One thing we've seen occasionally is pip running into this SSLError below.  Apache Bench doesn't show any oddities when we try to hit devpi directly.  Our SSL settings are the same we use with all our internal sites.  It's fronted by nginx:
ssl on;
  ssl_certificate ***;
  ssl_certificate_key ***;
  ssl_prefer_server_ciphers on;
  ssl_session_cache shared:SSL:10m;
  add_header Strict-Transport-Security max-age=86400;
Exception:
