Not really sure what is happening here, does your galaxy.ini file have
the following sections:

[filter:proxy-prefix]
use = egg:PasteDeploy#prefix
prefix = /galaxy

[app:main]

filter-with = proxy-prefix
cookie_path = /galaxy

If yes, it might be best to share nginx configuration and your galaxy
logs when this occurs so we can see what routes Galaxy thinks are
being accessed.
