Act depressing Error

A depressing error occurs.
I just finished the second version of the Upload Component and was about to perform a test. So I started the Act for a few minutes. Fortunately, nothing went wrong.
So I continued to add the test files and prepared to cancel the test in the middle of the result. So I clicked "cancel ".
I did not expect the dialog box on the recording page to die. No matter what it is, it will be terminated. Program.

The result is depressing to me. ie cannot open the test page!
This is good. Not only can the test page be opened, but other local pages cannot be opened! Prompt: Action cancel.
The same is true after the machine is restarted. Faint! The first reason is that IIS is suspended.
However, I can't find the cause of the error, so it is too embarrassing to reinstall IIS.

According to the prompt, open IE and check the connection options. The LAN connection settings are used.CodeThe port number is 8181. I am so depressed. When can I modify it !!
After modification, it will be normal. Depressing. It turns out that act is still doing this in the background! It seems that we have to use other tools for testing.
