Describe the bug
Hi, I had this issue. I cannot connect to a server with many nodes. But this server can be connected with some Java OPCUA connections. Also, If I change the programs in the server to some simple programs with fewer nodes, it can be connected with both ways.

How can I solve this issue? Are there any ways that I can configure to bypass this error? I am just using OPCUA to get access to very few nodes.

To Reproduce
Steps to reproduce the behavior incl code:

Expected behavior
How can I solve this problem? All I need is just make a connection and read write some of the nodes.

Hmm....the error says, that your server has reached the max. amount of sessions. So it doesn't seem to be a thing from the client (on the first sight).

Can you approve that your Client is the only one on the server(or that not many sessions are open)? Can you check the server limits how many opened Sessions are supported?
