However, navigating to port 80 results in an internal server error 500 - while navigating to port 1234 renders the expected output.
The log contains only "signal process started" entries.
What have I done wrong, or missed? How can I log a better (any!) description of the server error; I anticipate this is not the last time that would be useful.

If your backend is on the same host try using proxy_pass http://127.0.01:1234; instead proxy_pass http://example.com:1234;. NGINX invokes an internal name resolution logic before using DNS, since your server_name is the same as hostname in proxy_pass directive, this may be source of your problem.

Just remove proxy_redirect and send another request to the NGINX. If there is still Internal Server error investigate the log file.
Also, It will not harm if you check the backend (proxy_pass http://example.com) with curl from your server to getting sure your backend is healthy.
