Thank you for your answer.

I tried changing my IP address and this way it works.
The server probably keeps track of the number of subscriptions made by the IP address.

I found other open OPC UA servers on this link

github.com/node-opcua/node-opcua/wiki/publicly-available-OPCUA-servers

which seems to work fine.

Hello,

this appears to be a problem on the side of the demo server itself, not QuickOPC client.
We are already aware of the issue.

Either the demo server is simply used by too many genuine users - in which case we would increase the limits; or, it may be under kind of DoS (denial of service) attack - in which case we would take some countermeasures. Please give us some time to resolve this.

The demo server gets restarted regularly, so you may just retry later and be lucky so see it working.

Best regards

Hello,
the problem occurs when i try to subscribe to any of the objects on the OPC UA server even using the OPC UA Demo Application and subscribing to the preset EndPoint and Node.

OpcLabs.EasyOpc.UA.UAServiceException: OPC-UA service result - (no description available) = BadTooManySubscriptions.
---- SERVICE RESULT ----
StatusCode: {BadTooManySubscriptions} = 0x80770000 (2155282432)

The strange thing is that the program used to work just fine a week ago.
I've already tried reinstalling quickOPC. Any advice?
