127.0.0.1:8384 gui not accessible after shutdown/start syncthing

[lepidas (giorgos)]

Hi!

Through gui I shutted down the service in device Desktop(I wanted to be safe restoring a backup .config/syncthing/* to device Laptop,alltogether syncing with device home-server). Started again syncthing service with

sudo systemctl start syncthing@myusername.service

then gui was not accesible anymore from 127.0.0.1:8384. Edited ~/.config/syncthing/config.xml replacing 127.0.0.1:8384 with my the actual IP, after that gui was accesible with actualip:8384 but it’s something I don’t support, would like to get it back to 127.0.0.1:8384

Edited again ~/.config/syncthing/config.xml and added 127.0.0.1:8384

In Setings>GUI there is a notification

The GUI address is overridden by startup options. Changes here will not take effect while the override is in place.

127.0.0.1:8384

Something is overriding it on the command line or environment var.

I don’t know what to look for

Interesting is I put in ~/.config/syncthing a 2 days old backup and still the same problem (when the backup was taken there was no problem). I have to look somewhere else but syncthing. Thanx for watching anyway

Dumb question but are you sure you look in the home folder of the username starting the service? Maybe you’re not modifying the right config file. I made that mistake after creating a specific user for the service. If you have a start up option gui-address =<address>, I think it would override your xml config file.

Well no, there is only one user for the syncthing service. BUT! this post initiate me to open and read the /etc/systemd/system/multi-user.target.wants/syncthing@username.service file, and what I found was that the LAN ip of the machine was declared in ExecStart instead of 127.0.0.1

[Unit]
Description=Syncthing - Open Source Continuous File Synchronization for %I
Documentation=man:syncthing(1)
After=network.target

[Service]
User=%i
ExecStart=/usr/bin/syncthing -no-browser -gui-address="192.168.AA.BB:8384" -no-restart -logflags=0

I really don’t know how this happened, I have never touched this file before.

What and how I solved was to stop the service,

sudo systemctl stop syncthing@username.service

make a copy of the symlink and a copy of the service

sudo cp /lib/systemd/system/syncthing@.service /lib/systemd/system/syncthing@.service.bak

sudo cp /etc/systemd/system/multi-user.target.wants/syncthing@username.service /etc/systemd/system/multi-user.target.wants/syncthing@blades.service.bak

and edited the /etc/systemd/system/multi-user.target.wants/syncthing@username.service replacing 192.168.AA.BB:8384 with 127.0.0.1:8384

then enabled the service again for the symlink to be recreated from the edited file

sudo systemctl enable syncthing@username.service

and started the service again.

Thank you all.
