a) WiFi can be isolated from LAN, only allowing access to WAN.
b) WiFi stations are isolated from each other
Just for plan E ... check router settings, move PC from LAN to WiFI or vice versa

Plan C would be to try to install portable Arduino version and (when asking) allow all network communications in the firewall settings. Plan D then - don't use Windows (I'm out of plans actually...).

Special thanks guys, It worked well now.
After 2 hours of error and error xD , by the help of Wireshark.
Tried several crossing things as Cleared EEPROM of NodeMCU and trying my mobile hotspot and disabling windows and ESET firewalls, then tried a new NodeMCU and which then solved problem of network port appearance.
* Some firewall permissions were asked by this operation, as from java.
Then got back to my router. tampered with router settings, with negative effect.
lastly i restored router settings to default.
Now i run back all firewalls (rules applied) and all things are going well now.
So mostly the error was caused by some router settings.
Thanks
