Known issue, see #197 I need debug log.
What's server?

Server is a raspberry pi with Codesys license on it. i am using it as a PLC

[mikakaraila]

set DEBUG=all
node-red -v flowfile.json

I will need something to study this otherwise I cannot start to fix this.

Can you connect to same endpoint with UaExpert?

Can you connect to same endpoint with UaExpert?

I have the same problem and Yes, I can connect with UaExpert without any issues.

Usually my OPC UA Client node will just sit there saying "Connecting" and then eventually fall to "Invalid Endpoint", but sometimes it jumps straight to "Invalid Endpoint". Here is my log file:

OK, client works as it should, have you checked that server has client certificate on trusted folder?

There has been discussion and one comment says that AnsiC based servers will put certificate to rejected.
node-opcua/node-opcua#425

[nrok-hpotsirhc]

I just posted an other issue, but now I have the same trouble with this node.
Background is: I wanted to test if issue #205 is only related to version 0.2.83 as reported.

After updating from 0.2.83 to 0.2.84 I got also the "invalid Endpoint". The same flow was working before and is attached at issue #205.

[mikakaraila]

Verbose log actually does not help at all.
It has something bit deeper, can you set first:

set MAXARRAYLENGTH=1000

set NODEOPCUADEBUG=TRACE-REQUEST-RESPONSE-PERF-STATS

node-red yourflow.json

Then I can see what is really happening on client protocol level.

[mikakaraila]

Here is another way to check server endpoints:
node-opcua/node-opcua#693

What is hostname in your flow uademo or something else? Node-opcua will check this!

I checked this and actual endpoint is:
opc.tcp://UADEMO.prosysopc.com:53530/OPCUA/SimulationServer

Hi,

I've been trying to use your OPC-UA connector for NodeRed but encounter the same issue (invalid endpoint). According to what I found in this thread and linked ones, the endpoint should match exactly what the server provides, is that right? It doesn't seem to help in my case. I use Prosys OPC Simulator 3, and did a copy/paste of the full endpoint URL. I checked that the Docker image Node-Red runs under can resolve the server name. I also have other images on the same system that can talk to the OPC server without issue.

Log file:

What else could I try?

Thanks a lot!

Me again. Just tried with a standalone install of NodeJS on my Windows laptop (to compare with my previous try running Node-RED in a Docker image), copy/pasted the flow into the new instance, and it worked on the first try.
So, there must be something off with my Docker installation, or the image is maybe running an older version of Node-RED or something.
Sorry for the bother ;-)
