Edge Gateway | NIOT-E-TPI51-EN-RE (Connect)

To upload a server certificate for the communication with the HTTPS server
nginx, Node-RED, the Edge Server or the REST API from a file into the
Edge Gateway, if the corresponding key file has already been uploaded,
proceed as follows.
Ø Select option Service certificates within selection list (Selection list for
certificate type [} page 79]).
Ê Within window Certificates, a tree structure is displayed instead of the
list of preinstalled trustworthy certificates.
If the server certificate 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 cert.pem below nginx.
Alternatively: If the server certificate applies to the communication with the
OPC UA-Server:
Ø Within window Certificates, select the entry cert.pem below opcua.
Ê In both cases, the window Certificate Viewer now displays the data of
cert.pem.
Ø Click at button Uploadin the header of window Certificates.
Ê A file selection dialog appears:
Ø Within that dialog, select the certificate file to be uploaded! This file
must be present in the*.pem file format [} page 248].
Ê The certificate file is checked for correctness.In case of error, a
message appears indicating a defective file type and further processing
of the certificate file is terminated. For instance, this occurs if the file
does not have the extension *.pem or the contents of the file is not
coded in *.pem format. In case of success a security query appears
whether you really intend to replace the key file.
Ø If you are really sure not to need the current certificate file any longer,
click at Yes.
ð If this check is passed, the selected file is uploaded into the Edge
Gateway. During this, the formerly existing certificate within the Edge
Gateway is irreversibly destroyed. Thus, there is no possibility to restore
this certificate if no suitable backup is available. After a short delay , a
message is displayed indicating that the upload has been completed
and the Edge Gateway requires a restart
