It sounds like the request from the client includes a correctly-encoded
string %3E, while the request from nginx includes the decoded character >.

Can you show the location{} block in nginx that handles this
request? Perhaps there is something there that caused the decoding,
that can be changed.

Possibly you can use something like "tcpdump" to see the actual requests,
if the logs do not show the details.

Good luck with it,
