I am trying to connecting to the UaGateway with following encryption settings:
Basic256Sha256, SignAndEncrypt.
I am using various OPCUA Clients, here for example TwinCAT OPC UA Sample Client.
When connecting for the first time, the Clients certificate shows up in the UaGateway "certificates" section.
As i trust the certificate, the status of that certificate switches to "Trusted" and everything seems fine.
But then something weired happens, when i connect the second time:
The same certificate shows up again as untrusted (in the "certificates" section), and i cannot connect.
Also, i cannot set it to trusted (again?). The error message is: "Could not move certificate (...) to the trusted directory."
When i check that directory, i see that this certificate file is located there correctly.
To note: With UaExpert, this does not happen. There, once trusted, a certificate does not appear again as untrusted.
Also, i didnt experience this problem with the prior version of UaGateway.
Please help me, i need to connect to the UaGateway with a third party client!
Thank you very much in advance,
best regards

Hi Christoph,
First you should check the certificate, is seems that the UaGateway can not uniquely identify the Certificate, hence assumes that it is a "new" certificate (and adds it as "untrusted").
The Certificate (content) may not comply to the OPC Foundation specification.
