argument to your openHAB startup? I think the advice from @Denkermatic ought to solve the issue. Also, are you using Oracle JDK and not OpenJDK? You might find different results if that’s the case (in which case the common CA certificate might already be present and so no extra steps would be needed).
I am marking the related issue as “documentation” because I am confident that that is the root cause.
Hi, after update Ubuntu to v18, i got the same error.
I add extra java parameter, but this doesn’t help, Oracle Java is used.
What else can i do to get pushover works again?
