<div class="markdown_content"><p>Dear Forum,</p> <p>I have created a certificate for the WebServer in WinV3 and installed it on my computer, see picture webserver1.<br/> The name of my computer is "GGB", the certificate has been created under this name, and if I access the webserver via this name, it works all good, see picture webserver2.<br/> However if I access the webserver via the IP address, the browser shows the https page as unsecure, of course because, the certificate has been made for "GGB", see picture webserver3.<br/> This gets more interesting if I would like to access the webserver via another device where I must address it via the IP address.<br/> Now the question is, how can I generate a certificate what includes the IP address as it's name so I can access it externally? I'm looking for a general solution what works also on PLCs and not only on Windows with WinV3.</p> <p>Thank you,<br/> Gergö</p></div>
