I have a question regarding setting up an application server.
We're busy connecting a device on the lora developer portal so that we can receive data on our own server.
We've set up a server for now(https://iottest1.viperonline2.nl/) with a SSL certificate but we get the following error:
sun.security.provider.certpath.SunCertPathBuilderException unable to find valid certification path to requested target
We are unable to find what the problem might be(possibly something with the SSL certificate). Does anyone have any suggestions or can anyone help us?
Thanks in advance
