Unable to install node in Node-Red

Unable to install node in Node-Red

New Poster


I am trying to install node-red-contrib-opcua in my Node-red. When I initiate the installation, within a minute, my ctrlX Works goes unresponsive.
Despite a working internet connection and synced time, it requires a restart to access again. I can install other nodes, but for few nodes I am facing this issue.

Hello Andrew,
I will try to analyse...could you please have a look at the report directly at the beginning of the process.


Do I get you right, that other packages/lib node-red-contrib xyz can be installed - just several including the node-red-contrib-opcua arent feasible?
That means generell access to the internet is provided... and the following proxy-infos are unneeded and useless.

In case the access is not given this infos may help.
In case you operate in a company network please verify the access:
- Firewall exclusion necessary? 
- proxy with credential setting necessary? (e.g. Px.exe as proxy server)
- check/edit ctrlX- Proxy setup

Please have a look to topic "Node-RED OPC UA Invalid Endpoint"?


Plus can you provide the versions and the general setup you are using?
