As for the final error you are getting where Ditto is refusing to start, the error message seems to be truncated to the right. Could you pipe the result of `systemctl status ditto.service` on your VPS into `curl -i -F 'file=@-' https://0x0.st` and paste the link here?
The final command you would run is:
```
sudo systemctl status ditto.service | curl -i -F 'file=@-' https://0x0.st
```
It should spit out a link in response.
