Hello,
I have a private blynk server running on a linux Ubuntu 16.04.6 LTS box. Everything works fine except when the code tries to send out a push notification. It keeps giving the following error in the logs:
ERROR- Error sending push. Reason General OpenSslEngine problem
Any idea what might be the cause of that?
