Why syncthing and It's web gui not working after installing qbittorrent on raspberry pi?

Why raspberry pi can’t run as syncthing server and a torrent box?

There’s not enough information to deduce exactly what caused Syncthing to stop working, but if I were to guess, the network settings were changed.

  • What OS are you running on the RPi?
  • What steps were used to install qBittorrent?
  • What does Syncthing, or the OS, say when you try to start Syncthing?

Screenshots, and any other details (no detail is too small) would be very helpful.

I am running raspbian os and I use qBitTorrent as torrent client

Thanks, that’s a decent start, but more details are still needed otherwise it’s all just educated guesses.

In the meantime…

  • qBittorrent’s web GUI by default listens on network port 8080, which doesn’t conflict with Syncthing’s on port 8384.
  • qBittorrent, like other Bittorrent clients, isn’t just a client, it also acts as a server to share downloads with nearby clients. The local firewall, a network proxy or something else could be preventing access to Syncthing’s GUI (assuming that it’s still able to start correctly).

Could you post the output from the following shell command?

ps -ef

And also this command?

ss -ln

After reviewing the command outputs and screenshots, there are at least two unrelated issues…

Syncthing

Two lines from the first ps -ef output showed that Syncthing was running…

saman     6159     1  0 19:47 ?        00:00:00 /usr/bin/syncthing -no-browser -
saman     6168  6159  9 19:47 ?        00:01:53 /usr/bin/syncthing -no-browser -

… and three lines from the first ss -ln output showed a process was listening for connections on port 22000…

udp    UNCONN  0       0                                                      *:22000                                       *:*                                 
tcp    LISTEN  0       4096                                                   *:22000                                       *:*                                 

… in addition to port 8384:

tcp    LISTEN  0       4096                                         192.168.1.2:8384                                  0.0.0.0:*    

(Tip: Tweaking the ss command to ss -lnp will include the process name in the output, which might help with debugging. But since none of the other popular network services default to using port 8384 and 22000, it’s probably safe to assume that it’s Syncthing.)

So far things are mostly as expected. The one wrinkle is that Syncthing’s built-in web server has been overridden to bind to the network interface with IP address 192.168.1.2 instead of the default 127.0.0.1. There’s nothing inherently wrong with that, but it means adjusting the host firewall (if one is being used) if the intent is to access the web GUI via another host.

As for why Syncthing shuts down, I don’t think it’s due to qBittorrent.

From the first ps -ef output:

saman      845   662  0 17:58 ?        00:00:37 lxpanel --profile LXDE-pi

From the second ps -ef output:

saman     7620  7518  1 20:23 ?        00:00:11 lxpanel --profile LXDE-pi

Note how the PID (Process ID) numbers are different for lxpanel – it wasn’t the same desktop session:

  • Why did you log off and back on again between the two ps -ef runs?
  • How did you start Syncthing before doing the first ps -ef?

(I have a theory as to why Syncthing shut down, but will hold off until knowing the answer to the two questions above.)

Another consideration is that the version of Syncthing on the RPi is 1.12.1, which is around 2½ years old. Where are you getting the Syncthing package from? Unless there’s a reason to use an old version, really should upgrade to the latest release.

DNS

A related issue is trying to access Syncthing’s web GUI via the URL http://serverpi.local:8384/. The screenshot of Chromium shows the following errors:

  • “This site can’t be reached”
  • serverpi.local’s server IP address could not be found”
  • “ERR_NAME_NOT_RESOLVED”

Three different ways of saying basically the same thing – when Chromium tried to do a DNS lookup for the network address serverpi.local it failed.

Chromium/Chrome has an internal network diagnostic tool. Simply go to the special URI chrome://net-internals/#dns. Enter serverpi.local into the domain box and click the [Lookup] button.

Because Syncthing’s default was changed to listen only on 192.168.1.2:8384, then you’ll either have to fix your DNS setup in order to use http://serverpi.local:8384/, or always use the IP address version (http://192.168.1.2:8384/).

Thank you The hostname was server.local not serverpi. I need To access The web GUI from another device as I don’t have an attached monitor with the Pi. On the other hand, I need to make it easily accessible.
