The SSL issue isn’t going to be fixed - ever - according to this…

ESP8266 SSL connections down using Blynk_WiFiManager (ESP32 works fine, non-SSL 8266 works fine)

Hey everyone. Unfortunately that’s the only cure for this issue. We’re sincerely sorry for this, but due to some technical limitations, as well as the fact that we’re fully focused on the New Blynk Platform release, we’re not going to fix this particular issue. Ideally, we’d have to move all certificates to Let’sEncrypt, instead of self-signed certificates. But due to technical reasons, we cannot perform such migration (it would impact a much broader audience, make even more devices unusable…

With the non-SSL connection, have you tried specifying port 8080 instead of allowing the library to default to port 80?

Pete.
