      <description>&lt;P&gt;Hello,&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Thanks for contacting Databricks Support.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Based on the error message:&amp;nbsp;&lt;SPAN&gt;NPIP_TUNNEL_SETUP_FAILURE. It&amp;nbsp;indicates that bootstrap failed due to network connectivity issues between the data plane and control plane.&amp;nbsp;&lt;/SPAN&gt;&lt;/P&gt;
&lt;P&gt;&lt;SPAN&gt;Seems like you have already download the system log, please use Base64 decode tool to decode FAILED_MESSAGE. "2023/09/25 02:36:27 INFO vm_bootstrap.py:232: [Bootstrap Event] {FAILED_MESSAGE:(Base64 encoded) VGltZWQgb3V0IHdhaXRpbmcgZm9yIG5ncm9rIHR1bm5lbCB0byBiZSB1cA== }", you will get the RCA for the failure.&amp;nbsp;&lt;BR /&gt;&lt;/SPAN&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Timed out waiting for ngrok tunnel to be up.....&lt;/P&gt;&lt;P&gt;This doesn't tell me anything about what could be causing the issue though? What else can I check? has anyone else seen this before?&lt;/P&gt;</description>
