Today I am connected (via SSH) to my linux server and I saw on the terminal the following errors:

Blynk Server successfully started.
All server output is stored in folder '/home/igor/blynk/./logs' file.

This sequence of errors repeated 8 more times.
I got this error also with new version 0.16.2.

Hello. Thank you for reporting. This error is due to self-signed certificate which you probably tried to access via browser. I’ll fix this warning. You may ignore it for now.
