Hi,

A fresh install on Debian 10 having issues with fastcgi.  I am getting the following error2

d (104: Connection reset by peer) while reading response header from upstream, client: 169.254.0.184, server: _, request: "GET /netdata/ HTTP/2.0", upstream: "http://127.0.0.1:19999/", host: "mail.server.net"

connect() failed (111: Connection refused) while connecting to upstream, client: 1169.254.0.184, server: _, request: "GET /SOGo HTTP/2.0", upstream: "http://127.0.0.1:20000/SOGo", host: "mail.server.net"

PHP is not able to use ports 19999 and 20000. I look at another other server and nftables, ngingx.config, php conf are the identical.

Any sugestion.

Best regards,

Al

Ps  netstat  -ntpl does not show neither port open, what process or procedure listen to?
