RIDE under Windows can't connect to interpreter in WSL2 using localhost

[YsHaNgM]

Describe the issue you are having

RIDE keeps trying to connect to 127.0.0.1:4502 when host is localhost. The interpreter in WSL2 can't be found with that address, this results in connect error. Although a browser under Windows can connect to localhost:4502 when WSL2 interpreter starts in headless/ZeroFootprint.

Did you connect to an already running interpreter or start the interpreter from RIDE?

Connect to already running interpreter

How do you reproduce the issue?

Connect fail in RIDE: In WSL2, start interpreter RIDE_INIT="SERVE:*:4502" dyalog. In Windows RIDE, type: connect TCP, host: localhost, port:4502. Click 'connect'.

Connect success in browser: In WSL2, start interpreter RIDE_INIT="HTTP:*:4502" dyalog. In a Windows browser, type localhost:4502 in addressbar and hit enter.

For future newbies, IMHO:

In WSL2, start interpreter RIDE_INIT="SERVE:*:4502" dyalog.

should be: RIDE_INIT="SERVE::4502" dyalog

Note: leave out the asterisk
