[Pkg-nginx-maintainers] Bug#996475: More Detailed Description

[Martin G. Schöniger]

Dear Maintainers,

Sorry for my first incomplete mail. I first wanted to see how reportbug
works and didn't realize that it will send out mails without adding a
smtp server. So here comes a more detailed description.

After upgrading Debian from Buster to Bullseye (nginx 1.14 => 1.18, php
7.3 => 7.4) I am facing a problem with nginx.

First of all the needed system information:
OS: Debian Bullseye (11)
Kernel: 5.10.0-9
Architecture: amd64
Package: nginx
Version: 1.18.0-6.1

A server is set up for rtmp streaming only. Therefor it has a TLD with
frontend using SSL / https for upstreaming and showing the stream and a
second TLD using http without SSL for authentification.

In nginx.conf I use this line for authentification:
on_publish http://password.domain.de/secret.php;

This URL can be opened in a browser at any time. The streaming key in
the streaming device contains the credentials which are to find in this
file. 

Starting up the server everything works fine. A reboot takes some
seconds (~ 5). I can upstream when I use the right credentials. If they
are wrong the stream will not work. When I stop nginx and start it
again or when I reload it nginx will first need about 20s for starting.
The website of the stream will be available also secret.php will be
available, but upstream will not work anymore. /var/log/nginx/error.log
tells me "[error] 17337#17337: recv() failed (111: Connection
refused)". When I do "nginx -t" it will also take 20s, but then tells
me that everything is fine.

Usually I'm pretty shy to do a bug report as you might see in my
missing knowledge about "reportbug". In this case I'd like to report
it, because things seems to change after restarting nginx and this is
not as expected. 

Thanks for your time and your work
Martin
