While testing the uplink to my https server I got the message:
Server returned HTTP response code -1
Error in sending rest post to developer url https://XXXXX.nl, for device 83D6828ADAB95F42, payloadhex 000000. Error details: sun.security.provider.certpath.SunCertPathBuilderException unable to find valid certification path to requested target
I checked my site with
ssllabs.com and it seems there are no problems.
I also checked my website online, and it's ok too including the certificate.
What can I do next ?
