I am having issues reconnecting to an OPC-UA Server that is being hosted on a Siemens D245-2 after upgrading to 8.0.5. We had the connection made successfully with 7.9.13 but I know there were a lot of changes to how the servers authenticates in 8.0. I read the post here and while I was hopeful, I was unsuccessful. I can log in to the Siemens Web Server, and download the current certificate. However, after adding said certificate to the trusted list, and trusting the other quarantined certificate it still comes back after sitting for a bit. Also here is a partial snapshot of the two certs if that helps any.
ITDiagRootCA is the downloaded certificate and Winder was the quarantined one.
