Testing your edge agent 1.6 now and I get the following message when trying to use the OPC UA browse node with a bosch ML controller. (Security is disabled on PLC)  
**NotFoundError**  
EACCES: permission denied, open ‘/opt/losant/node\_modules/node-opcua-client/certificates/PKI/own/private/private\_key.pem’

Good catch Lars! Looks like a permission issue got introduced as part of our Docker bundling process. We’re investigating and will push out an update asap once it’s found. Stay tuned.

Hey Lars,

We found the issue in the Edge Agent, and we fixed it. The Edge Agent 1.6.1 is now available. Here is a link to our [change log](https://docs.losant.com/edge-compute/edge-agent-changelog/). Thanks again for bringing this to our attention.

Best,  
Erin

After I updated, shouldn’t 1.6.1 show up in here?

Hey Lars,

Actually no, there was no front end changes that needed to be made. You just need to [update your losant-agent](https://docs.losant.com/edge-compute/edge-agent-usage/#updating-the-edge-agent) since the fix is inside of that. We will be updating that list to avoid this confusion and it will go out with another (unrelated) fix soon.

Best,  
Erin

Ok.  
I can talk to the PLC now.
