Nexon Launcher

Error: An unknown network error occurred.

If You are experiencing the error shown above few seconds after trying running Nexon Launcher (nexon_launcher.exe), it might mean You do not meet minimum requirements, specifically the Adobe Flash Player installed requirement.

As result, following may appear in nexon_updater_debug.log:
ERROR: urlopen error SSL: CERTIFICATE_VERIFY_FAILED certificate verify failed (_ssl.c:590)
Traceback (most recent call last):

Other sources are mentioning same issue, where You have to disable PROXY in your connection settings at operating system.
