<div class="markdown_content"><p>Hello,<br/> I was using an old version of CodeSys, and adding this properties at CODESYSControl_user.cfg worked.</p> <p>But I updated the CodeSys version, and the error returned. <br/> In this version the <span>[CmpOPCUAServer]</span> can be configured inside the software, correctly?<br/> Is my configuration right (attachement) or I need to do something else?</p></div>

<div class="markdown_content"><p>Not sure what settings you have, but maybe the server isn't set up correctly? For example, check /etc/CODESYSControl_user.cfg (Linux) to make sure these items are in place:</p> <p><span>[CmpOPCUAServer]</span><br/> SECURITY.CommunicationMode=SIGNED_AND_ENCRYPTED<br/> SECURITY.Activation=ACTIVATED<br/> NetworkPort=4843</p> <p>NetworkPort is optional</p></div>

<div class="markdown_content"><p>Hello,</p> <p>I am having some troubles connecting my opc ua client to CodeSys Server with Sign or Sign &amp; Encrypt (Basic256Sha256).<br/> If I connect with None and None it works correctly.</p> <p>When I first execute it shows an error BadSecurityChecksFailed, so I go to the CodeSys Server and trust my certificate.<br/> After that, when I try to connect again the servers return an BadInvalidArgument. <br/> Using WireShark I can see that I am saying something null where CodeSys does not accept, but I can find what I am sending wrong.</p> <p>I am using this opc ua client <a href="https://github.com/nauful/LibUA" rel="nofollow">https://github.com/nauful/LibUA</a><br/> It works fine for others opc ua server.</p></div>
