OPC-UA error (Bad Too Many Sessions)

[heritopo]

Hello,
I am beginner about this topic.
I am trying to get multiple data from client (front cover station by FESTO) using python code. when i run the code, there was an error "Bad Too Many Session" as below picture.

server address : opc.tcp://10.48.134.10:4840
Signal address

Did the error appear due to code or server ?
Would you like to give solution regarding this ?

Thank you

BadToManySessions means that the OPC UA Server has no more resources for another Session!
Most Embedded small OPC UA Devices have just a few available, you need to check the manual for that device sometimes you can crank that session count up a little.

sorry @AndreasHeine,
i can't find the literature of OPC UA server in the module,
do you have reference ?
and i realize that i should not make discussion in here. it supposed to be in discussion session.
if possible, I will transfer my issue in the discussion session and close this issue.
Is it ok ?
thanks
