<h1 class="topictitle1">Common VPN Connection Manager error messages</h1>
<div><p>Describes of some of the more common VPN Connection Manager error
messages you may encounter.</p>
<p>In general, the VPN Connection Manager logs two messages in the QTOVMAN
job log when an error occurs with a VPN connection. The first message provides
details regarding the error. You can view information about these errors in <span class="keyword">iSeries™ Navigator</span> by right-clicking the connection
in error and selecting <span class="uicontrol">Error Information</span>.</p>
<p>The second message describes the action you were attempting to perform
on the connection when the error occurred. For example, starting or stopping
it. Messages TCP8601, TCP8602, and TCP860A, described below, are typical examples
of these second messages.</p>
