I think that the config snippet that you show does not lead to the error
log that you show.

Is there some other config in place?

If you add the line

  return 200 "Inside location /, request $uri\n";

before the proxy_pass, and make the same request, what response do you get?

You report that you can go to keycloak.my.domain in your browser and
things work.

Your config asks nginx to go to http://172.19.24.13:8080 using the hostname
signin.my.domain.

That is not the same as keycloak.my.domain. Possibly that difference is
a reason for things not working?
