The error message suggests that you have no gRPC proxy module 
compiled in.  Check the "nginx -V" output - my best guess is that 
you haven't updated the nginx binary you are running.

Note well that nginx 1.17.3 is obsolete long time ago and should 
not be used.  Consider updating to nginx 1.21.0 or nginx 1.20.1.

Note that "strings nginx" will look into "nginx" file in the 
current directory, while running nginx will look for the nginx 
binary in PATH.  In most cases these aren't the same thing.
