windows - Can't access 127.0.0.1

Question

I can't figure out when this started to happen, but the result is - 127.0.0.1 is not working on any port from anywhere (for example, browser says Unable to connect). Here are the results of my research:

1. localhost, COMPUTER_NAME and actual IP address all work fine
2. there is nothing special in my hosts file
3. ping to 127.0.0.1 and tracert do work fine
4. all the programs that have 127.0.0.1 hardcoded are not working (this point makes me disappointed the most, because I can't do anything in this case )

What else can I do to identify the source of problem and fix it?

UPDATE: as soon as Redis does work on 127.0.0.1 and both IIS and AzureStorageEmulator don't work I assume this is HTTP only issue.

Answer 1

Just one command did the work

netsh http add iplisten 127.0.0.1
