localhost refused to connect Error in visual studio

I have copied my solution file from another system and tried to run it on my machine: For this, I have gone to the project folder and deleted the previous solution file and copied the new one.

我已经从另一个系统复制了我的解决方案文件并尝试在我的机器上运行它：为此，我已经转到项目文件夹并删除了以前的解决方案文件并复制了新的解决方案文件。

Now, it started giving me error. connection refused etc. So, I got one solution from here: How to solve ERR_CONNECTION_REFUSED when trying to connect to localhost running IISExpress - Error 502 (Cannot debug from Visual Studio)?

现在，它开始给我错误。连接被拒绝等。所以，我从这里得到了一个解决方案：尝试连接到运行 IISExpress 的本地主机时如何解决 ERR_CONNECTION_REFUSED - 错误 502（无法从 Visual Studio 调试）？

According to it, I changed the port number from 1049 to 1052. It loaded and one of the pages gets loaded. But when I entered the desired login credentials then it redirected to the older port again, like this:

根据它，我将端口号从 1049 更改为 1052。它已加载并加载了其中一个页面。但是当我输入所需的登录凭据时，它再次重定向到旧端口，如下所示：

http://localhost:1049/Home/SearchFlight

and the error is:

错误是：

 This site can't be reached

 localhost refused to connect.
 Search Google for localhost 1049 Home Search Flight
 ERR_CONNECTION_REFUSED

Now, I don't know what to do from here. I have changed the port number to 1052 but still its pointing to 1049. What should i do now?

现在，我不知道该怎么办。我已将端口号更改为 1052，但仍指向 1049。我现在该怎么办？

I had a similar issue. Try this and it should work

我有一个类似的问题。试试这个，它应该可以工作

1. Go to your project folder and open the .vsfolder (keep your check hidden item-box checked as this folder may be hidden sometimes)

2. In the .vsfolder open the configfolder

3. See that applicationhost.configfile there? Delete that thing. (Do not worry it will regenerate automatically once you recompile the project.)

1. 转到您的项目文件夹并打开该.vs文件夹（保持选中隐藏项目框，因为该文件夹有时可能被隐藏）

2. 在.vs文件夹中打开config文件夹

3. 看到那个applicationhost.config文件了吗？删除那个东西。（不要担心它会在您重新编译项目后自动重新生成。）

Usually on local machine we are getting errors like This site can't be reached localhost refused to connectbecause we have self signed certificate configuration broken for local IIS Express.?Sometimes it happens when you change URLs in launchSettings.jsonor never configured self signed certificates on this machine at all.

通常在本地机器上，我们会收到错误，例如This site can't be reached localhost refused to connect因为我们为本地 IIS Express 设置了自签名证书配置。有时当您更改 URLlaunchSettings.json或从未在此计算机上配置自签名证书时会发生这种情况。

To fix self-signed certificate on the local machineyou need to:?

要在本地计算机上修复自签名证书，您需要：？

1. Delete .vs folder (requires to close Visual Studio 2017)

2. Run these commands in cmdAs Administrator:

   cd "C:\Program Files (x86)\IIS Express"

   IisExpressAdminCmd.exe setupsslUrl -url:https://localhost:12345/ -UseSelfSigned

2. 在 中运行这些命令cmdAs Administrator：

3. 确保您运行 VS2017As Administrator并检查问题是否已解决

Note: https://localhost:12345/is what is in your launchSettings.jsonfor HTTPS

注意：https://localhost:12345/是什么在你launchSettings.json的HTTPS

I solved a similar problem by listing bound IP addresses in a cmd window running as admin:

我通过在以管理员身份运行的 cmd 窗口中列出绑定的 IP 地址解决了类似的问题：

netsh http show iplisten

Then, one by one, blowing them all away:

然后，一个一个，把它们全部吹走：

netsh http delete iplisten ipaddress=127.0.0.200
netsh http delete iplisten ipaddress=127.0.0.2

Unfortunately, none of these answers worked for me. This answer finally did for Chrome only. Unfortunately, you have to do it each time:

不幸的是，这些答案都不适合我。这个答案最终只适用于 Chrome。不幸的是，您每次都必须这样做：

1. Open this in your browser: chrome://net-internals/#hsts
2. Go to Delete domain security policies
3. Enter "localhost"
4. Restart browser

1. 在浏览器中打开它：chrome://net-internals/#hsts
2. 转到删除域安全策略
3. 输入“本地主机”
4. 重新启动浏览器

Google Chrome redirecting localhost to https

谷歌浏览器将本地主机重定向到 https
