I have a problem with NMA.Before It was working very well, I just checked email notification and it works.
Now each time OH want to send a notification I got:
2018-03-16 14:20:36.869 [ERROR] [g.openhab.io.net.http.HttpUtil] - Fatal transport error: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 2018-03-16 14:20:36.887 [WARN ] [a.nma.internal.NotifyMyAndroid] - Can't parse response from NMA: null java.lang.NullPointerException: null
I have update NMA add-ons, but no change.
Any idea why ?
