Epic groov with codesys and opc ua


I’ve done an application with codesys on an epic groov. To share the variable with groov view, i use an opc ua server. I added in groov view in devices and tags a new device (type opc ua server with this address : It works very well, i find my opc ua variables , so far so good. But sometimes i got errors as show on the picture. Around 3 or 4 times by day.

Do you have any idea about how to solve this issue ?

Thanks a lot,
