    <description>&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Recently, I replaced my self-signed cert on the MC due to its expiry. Subsequently, all sensors were updated with this latest copy of the self-signed cert. However, each time I update the sensor signature, I got an error msg &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;"TLS Trusted Host Certificate difference found, updating sensor certificate for the MC.&lt;/P&gt;&lt;P&gt;The trusted certificates on the sensor &amp;lt;IP addr&amp;gt; have been updated".&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Then the update failed with an error msg &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;"The host is not trusted. Add the host to the system's trusted TLS certificates".&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Any helps will be greatly appreciated.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thx.&lt;/P&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Try this:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Login to your sensor;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;sensor# configure terminal&lt;/P&gt;&lt;P&gt;   sensor(config)# no tls trusted-host ip-address &lt;IP address="" of="" mc=""&gt;&lt;/IP&gt;&lt;/P&gt;&lt;P&gt;   sensor(config)# tls trusted-host ip-address &lt;IP address="" of="" mc=""&gt;&lt;/IP&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If this does not solve your problem, you may have to remove the old certificates from the sensor. For that you may have to use the 'service account'.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
