iis - asp.net waiting for localhost forever

Question

Suddenly this morning I turned on my computer and launched visual studio... And no matter what I tried and whether I run or debug, and whatever the browser is ( chrome / firefox / IE 11 ) it is waiting for localhost forever.

If I deploy it to azure, by just checking in ( continuous integration ) it works like a charm

I've read both:

• Waiting for localhost, forever!
• How to figure out why my local host site takes so long to load?

As I write, it has been waiting for localhost for more than 15mins. I restarted VS, even rebooted the computer... tried the ipv6 disable stuff on firefox...etc

I noted ( do not know if it is useful ) that Replacing localhost by 127.0.0.1 throws:

Bad Request - Invalid Hostname
HTTP Error 400. The request hostname is invalid. 

also my C:WindowsSystem32driversetchosts ( unchanged )

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost

Any idea ? I've not been able to show a single localhost page in 3hours.

Check firewall for blocked ports, change dynamic ports of application to some fixed port.
