Firefox can't find the server at www.localhost.com - asp.net

When i run my asp.net application it shows error on web page
"Firefox can't find the server at WWW.localhost.com"
I am using Visual Studio 2010 Ultimate and Windows 7 OS and Browser Firefox
Please Give me super and Permanent solution as much as fast because i have to complete my asp.net project so soon

try using
http://localhost:80/
80 is the port number.. change accourdingly
or if u run directly then u have to change the configuration from
www.localhost.com to http://localhost

I hope you are putting the URL in a correct way i.e., http://localhost:portnumber
If you are doing above correctly and page is still NOT showing, this maybe due to some proxy you maybe using. See the below image, highlighted option is showing that I don't want proxy to resolve my loopback addresses.
This is also possible that you are using Internet Explorer's settings for proxy, the same option also present in internet explorer.

Laragon Sites-Enables stopped working

I have been learning the Laravel framework and I used Laragon to get started. Laragon sets up my web server and my Hosts file so that I can access my work through the browser. Normally, I would boot up the server using the fancy "Start" button in Laragon and then go to the browser and type in "myFirstApp.dev" and my site would show up. Now I am getting an error in the browser that says "This site cannot be reached" (as shown in image1.jpg). How can I fix/diagnose the issue? Has anyone else ran in to this issue?
.
Found the answer to my own question. If anyone runs in to this same issue, here is an explanation. Google released Chrome v63 which forces all .dev domains to https. To fix this either enable SSL in Laragon or chance the domain extension your projects (.test for example). This will require changing your hosts and {Laragon Root}\etc\nginx\sites-enabled files.

Site functions locally, "Internet Explorer cannot display the webpage" on server

I have an ASP.Net Website (not a web app, fwiw) that builds and works just fine locally through IIS on my dev laptop.
However, when I publish it to our QA box and try to view while I'm remoting into that server, I get a message from IE saying "Internet Explorer cannot display the webpage". Firefox just spits back a quick "Connection Timed Out"
There is absolutely nothing in the event log nor the IIS log about this. I'm unsure where I can look for more info.
I'm fairly confident it is an ASP.Net issue. I can install a sample site from our vendor, Ektron, into IIS and it will run. If I overwrite the sample's web.config with my own, it continues to run. If I then blow away the entire sample site and copy over my site from my local, I'll get the message about how "Internet Explorer cannot display the webpage".
I've tried to keep the environments as close together as I can. Both boxes are running IIS 7.5 under an integrated app pool for .Net 4.0. I browse via localhost on dev and via an IP on the server.
I am not terribly familiar with the Website template, so I might be missing something obvious (I hope!). I'm hoping someone can provide some guidance into how I can get more info on what the heck is going on so I can resolve this issue.
UPDATE
I think I'm getting closer. By using Fiddler (thanks for the suggestion, Amy!) I notice that it redirects the request to SSL. SSL requires a different license from our vendor, so that might be it. I'm still trying to understand why that redirect is taking place, but at least I have something now to look at.
I'd look into the SSL settings in the web.config / IIS - settings for Mime Types and also into Ektron's MIME Types in the MimeType.config file. I found that some .aspx pages like (ekajaxtransform.aspx) weren't functioning correctly because of firewall/proxy issues/restrictions.
Hope it helps. :)

Bypass Certificate Error

Is there a way to bypass/ignore/disable certificate errors ? I'm encountering this on IE8 and the server is using IIS 7. The situation is I created a asp.net website and Im accessing this website using "https". My other website got no problem with this scenario but my other website does. I just want to do the trick within web.config or any other way except (server side code, creating Self Signed certificate, redirecting the website).
Thanks In Advance!
why are you seeing error to begin with? if you don't have certificate installed then make sure your not using HTTPS anywhere on your site.
its browser based...you can not control the warning message.
In IE follow the steps below. It works for me.
Click Tools and select Internet Options
Click the Security
Select "Trusted Sites" icon and set the Security level to "Medium Low".
Close all the Windows. Then open the browser.

"Internet Explorer cannot display the webpage"

I have an application that displays PDF files via Crystal Reports in a new window to the user. This works perfectly on my development machine and when accessing the site directly on the production server (remote desktop running browser installed on server) but when i access the site from the out side over the internet i get the error. Other reports display fine and this report used to work until i recently made some changes and re-installed the site. All code is in try ... catch but not info is being written to my error files. Cant figure out why it would work locally on the server but not over the internet and only this one report.
Have tried the System.Web attributes maxRequestLength and executionTimeout.
The Server is:
Windows Web Server 2008
IIS 7
Framework 4
This turned out to be an issue with the crystal report file, i never found out exactly why but i narrowed it down to one of the fields causing the problem, remove the field and no problem. I think it may have been linked to the reports xml based data source but cannot prove it.
Probably a firewall setting. Please make sure your firewall explicitly allows incoming connections to the TCP port 80 (or 443 for https, or anything else if you are accessing the site via another port) and try again.

Website on IIS different than on Apache

I developed a website and published it on a LAN computer running IIS 6.0 all through my testing phase to make sure it looked correct and worked with all browsers. I heavily used CSS for my layout, a small amount of javascript and ASP only for Server Side Includes. The layout was tested in Chrome, Firefox, Opera, IE8 and Safari. All working as intended.
When I went to upload my completed website onto my domains host, the website came out looking completely different as well as the css drop-down menu not working. The following URL shows the differences (sorry both screen caps are combined because of link limit on SO):

After investigating a little bit, I discovered that hosting site runs Apache as their server. I also ran the ASP command Request.ServerVariables("SERVER_PROTOCOL") on both hosts and discovered that my IIS testing host returned SERVER_PROTOCOL: HTTP/1.1 while the Apache host returns SERVER_PROTOCOL: HTTP/1.0
I am somewhat stuck on where to go from here. Is this difference in server protocols causing my css to be interpreted incorrectly on the Apache server? Can I do anything about it considering my domain hosted server is out of my control? Am I completely off track and should look elsewhere?
CSS is interpreted by the browser, not the web server. The problem probably has to do with the way your hosting provider supports ASP sites (if it supports that at all).
This smells like wrong file references.
Are you sure the live server is not just getting a fatal error and aborting the execution of the page?
Have you checked your error log in your host control panel?
there could be some \ (backslash) instead of / (slash) in some path definition. IIS interprets backslash or slash in the same way (Apache doesn't).
