ESP32 Wifi SSL Issue with local Blynk Server


#1

I’ve setup a local Blynk Server on Ubuntu. works nice, i just could not get the ESP32 Wifi SSL Example to work with my Server. I use letsencrypt certificates,ports set and forwarded. blynk log states:

DEBUG- Unsecured connection attempt or not supported protocol. Channel : /XX.XXX.XX.XXX:49090. Reason : javax.net.ssl.SSLException: Received fatal alert: unknown_ca

What am I missing?


#2

…as usual, after hours of trying and googling, figured it out 5min after posting:

#define BLYNK_SSL_USE_LETSENCRYPT

before including the lib did the trick
