Ê Within window Certificates, a tree structure is displayed instead of the
list of preinstalled trustworthy certificates.
If the server certificate corresponding to the key file applies to the
communication with the HTTPS server nginx, Node-RED, the Edge Server
or the REST API:
Ø Within window Certificates, select the entry key.pem below nginx.
Alternatively: If the server certificate corresponding to the key file applies to
the communication with the OPC UA-Server:
Ø Within window Certificates, select the entry key.pem below opcua.
Ê In both cases, the window Certificate Viewer is empty now (Text No
data).
Ø Click at button Delete in the header of window Certificates.
Ê A confirmation prompt whether you really intend to delete the key file
key.pem corresponding to the server certificate, is displayed.
Ø If you are really sure not to need the current key file any longer, click at
Yes.
ð The key file is removed from the Edge Gateways.
Note:
If a server certificate related to a specific service such as OPC UA
Client or Server, is removed, then the affected service will not be
available until an according key for this certificate is uploaded to the
same position within the tree structure as that of the formerly
removed key.
