Lot of these errors

I am getting log file full of these errors, especially when i use to load the local address of lovelace (i mean https://192.168.x.xx:8123).

2019-04-11 12:16:09 ERROR (MainThread) [homeassistant.core] Error doing job: SSL handshake failed

From where they come from? How to fix them?
EDIT: running HA 0.91.3. Also i noticed these errors do not come when using duckdns address…
