==Troubleshooting==
The following errors may or may not occur, here is how you deal with them:
<ul>

<li>"<code>node-opcua not found</code>"
<br>may occur if the module path to opcua is not set correctly in the Expecco settings.
<br>This may also occur with a global opcua installation with Windows10; 
if this should apply to you, do a local installation instead.

<li><code>"ERROR_write other</code>"
<br>may occur if you manually shut down a node server which the still running bridge tries to access.

<li>"<code>port undefined</code>" or "<code>already in use</code>"
<br>may occur if you are trying to start an opc server while another still holds the tcp socket you are trying to use.
<br>If your created session runs into a timeout, it may be that node
still holds an expired session token.
<br>In that case (within expecco) navigate to "<i>Plugins</i>" &#8594; "<i>Bridges</i>" &#8594; "<i>Node Bridge</i>" &#8594; "<i>Disconnect All Open Connections</i>" 
and try again.
