Qnap Dashboard don't work

I don’t think so. I’m telling not about identity, but about email address specified in the application. Does it have round branches ( and ) in the value?

It’s not bind to your identity.

This is not needed.
Please, ssh to your QNAP, get to command line and take result of the command:

docker inspect storjlabsSnContainer -f '{{.Mounts}}'
  1. Use values for /app/identity and /app/config in the setup step: Storage Node - Storj Docs
  2. Then run the node: Storage Node - Storj Docs (substitute your values).
  3. Then remove the QNAP app.
  4. To automatically updating your node run watchtower: Software Updates - Storj Docs

To have an access to your dashboard you can use an remote access: How to remote access the web dashboard - Storj Docs
If you want to access it only inside your local network, then you can modify your docker run command and replace -p 127.0.0.1:14002:14002 to -p 14002:14002

To update any parameter you need to stop and remove the container:

docker stop -t 300 storagenode
docker rm storagenode

Then run it back with all your parameters include changed ones.

If you would use a text editor to form docker run command, then please use only plain text editor, do not use any wordprocessors - they can replace a straight quotes to curly ones, double dash to hyphens and so on.
