Hi,

I try to connect to a Wago SPS (750-8202) but I always get an exception: Bad_OutOfMemory (0x80030000) “Not enough memory to complete the operation.”
Same is true for the Prosys OPC UA Client. When I use the UaExpert as client or Eclipse Milo as SDK it works.

I try to connect with the NONE:NONE profile and tried to turn off every additional feature like a status listener.

I have no clue how I proceed. Do you have any idea what could cause the failure? Did you coincidentally tested the SDK with a WAGO SPS?

Here is the stack trace….
