"Lost connection, trying to connect" Loop

[cosimo1234]

Hi, i'm new with OPC UA and i have a problem with configuration. Let my explain,

I've 6 OPC UA Server i want to connect to. Every server has the same level of security but but UaGateway can only connect to one of them with Anonymous e None. For the others i have a loop, them connected and then lost connection and so every few seconds.

Every Ua Server has same Uri and i red on forum that UaGateway can't connect to two servers with same Uri. Coul be this the problem?

Thank for answer

Hi,

yes the UaGateway can connect up to 50+ UA servers and combine their address space into one, called aggregation. The connection to each underlying UA server is separate and has individual, separate/different Security Policy, and individual User Authentication, if any. The URI of every instance of the underlying server is unique (typically by having hostname/IP being part of that URI), further more each underlying server has different certificate, matching that URI.

When configuring the underlying connections with ConfigTool, make sure you NOT use the "recently used", but instead "custom discover" each of them separately. Just to make sure they are different and the matching certificates are used.
