Running for two days and now won't start

Here is log message: syncthing-gtk: Configuration directory: ‘/home/aquiles/.var/app/me.kozec.syncthingtk/config/syncthing’ syncthing-gtk: Failed to create configuration directory syncthing-gtk: [Errno 17] File exists: ‘/home/aquiles/.var/app/me.kozec.syncthingtk/config/syncthing’ syncthing-gtk: Syncthing configuration directory: /home/aquiles/.var/app/me.kozec.syncthingtk/config/syncthing 17:53:35 WARNING: Key exists; will not overwrite. 17:53:35 INFO: Device ID: EMEMKUW-C6VRVDT-WAPHPSK-TSV2LSJ-G77IBAM-RWGDXN3-VU22LV2-MXJ6AAE 17:53:35 WARNING: Config exists; will not overwrite. syncthing-gtk: port 8080 is not available syncthing-gtk: chosen port 8081 syncthing-gtk: Traceback (most recent call last): File “/app/lib/python2.7/site-packages/syncthing_gtk/wizard.py”, line 711, in save_settings with open(self.parent.st_configfile, “r”) as conf_file: IOError: [Errno 13] Permission denied: u’/home/aquiles/.var/app/me.kozec.syncthingtk/config/syncthing/config.xml’

I’d suggest not to use syncthing-gtk as it’s not actively maintained anymore.
