Syncthing not working (userdata-error?) Topic is solved

[Joulinar]

As you can see on your first output, dietpi_userdata is pointing to your HDD 14BEBE5BBEBE3558

Code: Select all

dietpi_userdata -> /mnt/14BEBE5BBEBE3558/dietpi_userdata

You don't have 2 folder dietpi_userdata because it's same.

pls restart your system and post output of systemctl status syncthing.service afterwards.

[Mr.Roboto]

Thank you so much for trying to help me!

ok looks like your Syncthing Gui is LISTEN on local internal interface only.

Code: Select all

Okt 08 14:35:52 MediaPi syncthing[649]: [7VQ4O] INFO: GUI and API listening on 127.0.0.1:8384

let's check configuration file

Code: Select all

cat config.xml|grep address

[Mr.Roboto]

cat: config.xml: Datei oder Verzeichnis nicht gefunden ("file or directory not found")

[Joulinar]

Ah sorry my fault, should be following

Code: Select all

cat /mnt/dietpi_userdata/syncthing/config.xml|grep address

PS: kein Problem, ich verstehe die Fehlermeldung

[Mr.Roboto]

Code: Select all

<address>dynamic</address>
<address>127.0.0.1:8384</address>

[Joulinar]

ok this should fix it

Code: Select all

sed -i 's/127.0.0.1:8384/0.0.0.0:8384/g' /mnt/dietpi_userdata/syncthing/config.xml
systemctl restart syncthing.service

[Mr.Roboto]

So sorry, but web ui stilll does not work. I keep getting page loading error.

[Joulinar]

ok let's check if Syncthing is LISTEN on port 8384

Code: Select all

lsof -i -P -n | grep LISTEN

might be lsof is not installed on your system. Just use apt install lsof if it's missing

[Mr.Roboto]

Doesn't look like it:
