Suddenly the console port seems unavailable

[n3mmr]

I have my Serviio 2.3 running in a jail under TrueNAS Core 13.3.
The jail has the address <home-network>.199

IP scanners find the serviio jail and my media players can play stuff from the serviio dlna.

However, when I try to connect to "<home-network>.199:23523/console" with my browser, the connection times out. Same for the mediabrowser.


I need ideas on what might prevent reaching the console.

Just to confirm: this sandboxed place you run Serviio, the URL uses the .199, but not as a port? I could see your internal DNS have trouble resolving a URL that is using a number as the root of the network name. I don't know if that's something you've done intentionally, or if the system you're using did that by default. I could see the DLNA still functioning despite the naming, since it's using UDP and uPNP to discover the services. But I just have a hunch (with nothing to back it up) that your network name is the issue.

using the DNS resolver to give the jail a name I tried https://serviio2.rhg097:23523/console and got the same failure exactly.

I've had this serviio in that jail since 2.3 came out and the FreeBSD crowd hacked up a "port" that I found in freshports.org, which is the FreeBSD way to add non-BSD SW to the commonality.

The console has worked flawlessly in the manner described in my OP since I installed that jail, until a few days ago.

I got ssh running so I could run stuff in a better terminal window.
And I tried this inside the Serviio2 jail:

  Code:

[hans@Serviio2 ~]$ wget https://localhost:23523/console
--2025-02-20 12:51:34--  https://localhost:23523/console
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:23523... failed: Connection refused.
Connecting to localhost (localhost)|127.0.0.1|:23523... failed: Connection refused.


So, nobody seems to be listening! Huh?????? What the f....!

[n3mmr]

The port is 23423 for unsecure connection!

Gaah!

[atc98092]

Yes, 23423 is a standard port, while 23523 requires a security certificate of some sort installed on the machine with a FQDN that matches the machine. Beyond that, I'm outside my knowledge area with sandboxed or jailed apps. Hopefully someone else can step up here with some ideas.

And it now works.
