The only messages in the error log were ones for hours before and for
hours after the ³problem², of the form:

2014/06/17 17:14:16 [error] 28165#0: *1508 no user/password was provided
for basic authentication, client: 11.12.13.14, server:
app.test.example.com, request: "GET / HTTP/1.1", host:
³app.test.example.com"

There was nothing related to the 502 errors around the time of the first
request that failed with a 502 error code. The access log shows quite a
few requests failing with a 502 status code from that point forward, up
until the time that I restarted nginx.
