this error/ issue happen sometimes in windows 10 and all other windows. Reason of behind this issue is misconfiguration of network adapter and maybe windows problem. you can visit my website for helps in network configurations.
Um, NO. This is NOT a misconfiguration of the adapter or any other connectivity issue. It is a GUI issue where a corporate VPN connects fine via the VPN connections settings panel, but not from the task tray due to a bug in the tray. FAIL.
