OPCUA Connection issues - alo_dafo - 27-05-2025 Good morning all, I have a customer that tries to connect to the eWON OPCUA Server from their .NET application OPCFoundation.NetStandard.Opc.Ua library. They have set the certificate to trusted in the eWON and can connect successfully via uaExpert, but not with their application. Error message in their application is BadUserAccessDenied. The event log in the eWON shows -28611 secu-Authentication failure (From OPCUA server, localhost) The connect via WAN port (WANItfProt = 2 Allow all), same way as with uaExpert. • Endpoint #4: SecurityPolicy=Basic256Sha256, SecurityMode=SignAndEncrypt • UserTokenType=UserName, SecurityPolicy=Basic256 (as published by the server) • Password encrypted using: • Algorithm: http://www.w3.org/2001/04/xmlenc#rsa-oaep • Padding: RSA-OAEP with SHA1 • Server's public certificate (thumbprint verified) • PolicyId = "UserName" (case-sensitive and validated) |
