No problem. There are two different places involved, and the commands go in different places.
If the prompt says this:
lisaalfa@lisaalfa:~$
that is the VPS terminal.
If you are in PowerShell or Terminal on your laptop before SSHing into the VPS, that is your laptop terminal.
The dashboard command goes on the VPS.
The SSH tunnel command goes on your laptop.
Do this in this order:
On the VPS, keep this running:
hermes dashboard --host 127.0.0.1 --no-open
If you see the normal lisaalfa@lisaalfa:~$ prompt immediately after running it, then it may not still be running. Start it again and leave that terminal open.
Then go back to your laptop. Open a fresh PowerShell or Terminal window on the laptop. Do not SSH into the VPS first.
In that laptop PowerShell/Terminal window, run:
ssh -L 9119:127.0.0.1:9119 lisaalfa@YOUR_VPS_IP
Replace YOUR_VPS_IP with the real public IP address of your VPS from your hosting provider’s control panel. Do not use dash.mydomain.com; that is just an example dashboard domain, not your VPS IP.
After that SSH command connects, keep that PowerShell/Terminal window open.
Then open this in the browser on your laptop:
http://127.0.0.1:9119/
If you ran the SSH tunnel command from inside the VPS, it will not help your laptop browser. The tunnel has to start from the laptop.
It is okay to run the local dashboard command again if needed. Do not ask Hermes to set up the dashboard or subdomain again right now. The dashboard already works locally on the VPS, and the subdomain path is the part we are intentionally not using for this recovery.
For learning what is possible, yes, the docs are the right place to start. Good pages for what you asked about:

I would use the docs to learn, but I would not ask Hermes to make server permission or Docker/dashboard changes from the docs until this recovery is fully done.
