Installing Root CA Certificate
If you are using the ThingWorx hosted server, and the current date is within the
Valid date range on the certificate, then no additional certificate steps are
required.
In order to connect from sample application to the ThingWorx server via https
protocol, it should be configured to trust to the root certificate of the SSL (https)
certificate of the server.
The certificate (
root_ca.cer
file) copied to the MVI56E-LDM belongs to Digital
Signature Trust Co®, a well-known Certificate Authority, which is a parent of SSL
certificates used in ThingWorx trial servers, hosted by PTC. Copying this
certificate to the MVI56E-LDM makes sure that the sample application is trusted
by the PTC servers. No additional certificate steps are required.
It is worth mentioning that servers hosted by PTC have their https certificate
issued by free certificates provider
Let’s Encrypt ®
).
Therefore, if you get a certificate for local ThingWorx installation from
Let’s
Encrypt
, it will be accepted by the sample application without additional
configuration changes.
