Is there any pattern to the errors that you can see?
Are they all coming from a particular browser version, for example?
For now, I can’t see any pattern and the error logs (how they are
formatted now) does not help me, they don’t pass the user-agent data.

It looks to me like nginx does not expect the quotes after the =.
They are unnecessary, but I think that they are possibly allowed by
If they are allowed, then nginx should probably be changed to accept
them. If they are not, then the client should probably be changed not
to send them.
Yes, I think if that is the case, nginx could be more permissive…

It looks to me like something – client, server, or just the display –
has gotten confused and mixed together the Cookie: header with probably
an Accept: header. I don’t think there’s much that can be done about
this, apart from try to identify the culprit and see if it is something
repeatable and fixable.
I see that in this case maybe the client corrupted the cookie data
unfortunately… Anyway I will leave here another log entry with the same
error but a different value in the cookie.

If it is an identifiable problem in nginx, then I’m sure there’ll be
interest in fixing it.
