<div class="gmail_default">Hi, everyone --<br>
<br>
</div>
<div class="gmail_default">My Jupyter development app is now configured and functional, such that the app launches and connects to the compute node I have provisioned with TurboVNC and websockify (still testing).<br>
<br>
</div>
<div class="gmail_default">Being after 4pm local time, I have two problems that are preventing the actual connection.<br>
</div>
<div class="gmail_default">-- After launching a session, a "Connect to Jupyter" button is presented. After clicking through, I don't know how to satisfy the password request in the browser window. Post connection
documentation doesn't make enough sense to me.<br>
<br>
</div>
<div class="gmail_default">-- Perhaps related to my failed password attempts, I'm now also experiencing a database connection error preventing any further evaluation:<br>
<pre>sbatch: error: slurm_persist_conn_open_<wbr>without_init: failed to open persistant connection to smaster:6819: Connection refused
