I have a Linux 64Bit soft PLC that is supposed to run a web visualization.
I have a valid license for the runtime - the dongle is inserted to the device and is read successfully by Codesys.
When I try to open the web visualization I see the red loading symbol that tells me that an error happened.
I can log in to the project via the CodeSys IDE and live debug - the application works fine without exceptions.
In the log under "Device" I can see these two messages:
TlsCreateContext: Creating the TLS context for namespace 'WebServer' failed.
TlsCreateContext: Failes to read certificate './PKI/cert/server.cer' in namespace: 'WebServer'
Has anyone experienced this issue before? How do I resolve it?
Of course I have rebooted the device multiple times and have even re-installed the runtime. I have also tried going back to an old backup of the project where the web visu was still working - but I get the same error...
Best Regards
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
hm.. strange, could us use the Security Agent to generate a selfsigned certificate?
Do you want to access the webvisu pages by http: or encrypted by https: ?
Anyway in my config it work without problem even I see this error (warning) too..!
Could you try to change the port in case there is another service running on 8080? [CmpWebServer]
WebServerPortNr=8081
for a test..?
This works without Security Agent.

Hi, thank you again for your input.
I could not find any documentation on the Security Agent and the store seems to be unavailable now.
For now it would be enough for me if I could access the web visu at all, so http would be fine.
