Dashboard on distributed.SSHCluster returns 404: Not Found

What happened: When starting a Dask distributed.SSHCluster I cannot access the Dask dashboard. The server returns 404: Not Found.
However, the dashboard is accessible when starting a local cluster via client = distributed.Client().

What you expected to happen: I'd expect the Dask dashboard to show up.

Minimal Complete Verifiable Example:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install dask distributed bokeh jupyter-server-proxy asyncssh

import distributed
cluster = distributed.SSHCluster(["127.0.0.1", "127.0.0.1"], remote_python='YOUR_DIRECTORY/.venv/bin/python')
client = distributed.Client(cluster.scheduler_address)
print(client.scheduler_info()['services']) # Output: {'dashboard': 8787}
