Error logs usually don't include that information. Access logs frequently
do, and it is often possible to tie log lines together based on timestamp
and url. If you have the information, it may be a useful data point to
see whether the problems are associated with only one specific old version
of a browser, where newer versions of the same thing browser no problem,

Reading more closely, I still can't tell whether the surrounding quotes
are actively forbidden; but they are certainly advised against unless
the cookie was flagged as new, which I think nginx default ones are not.
I would tend to invite the client to become fixed, or invite the user
to change clients. But that's because it costs me nothing to do so.

There the cookie named "sid" has no value. I suspect more information
will be needed to know what is happening here -- was it somehow set
blank by something else running through nginx? Or is it an attempt by
the client to see what happens when they manually change things?
Good luck with it,
