Serv-U cannot connect to server 127.0.0.1 and port 43958

Cause of Serv-U "unable to connect to server 127.0.0.1, port 43958"
I can't find out what the problem is. I checked the information on the Internet for the following reasons:
43958. This is the local management port of Serv-U. Only 127.0.0.1 connections are allowed. This Port cannot be connected because:
1. Permission error. (I will add the system and grant the default permission to solve the problem .)
2. Connection to 127.0.0.1 may be disabled due to software issues;
3. This problem may also occur during hacker attacks.

Serv-U "unable to connect to server 127.0.0.1, port 43958" error
1. Solution
After the serveu plug-in is installed, Seru cannot run online

My problems and solutions:
The operation permission of the Serv-U service is granted to another user. The solution is as follows:
Run services. MSC to find the server name of Serv-U.

First, go to user management (Computer -- Right-click Properties -- user management) to change the password.
In the preceding figure, change the password in the following section. Run to solve the problem.

Or refer to the following method:
Because files need to be transmitted frequently between two computers, Serv-U is installed on their own computers, which was very useful a year ago. After the Chinese New Year, it was hard to use, failed to log on to another instance using CuteFTP, and then go to the local machine to check

4. Because Serv-U is mostly a cracked version, check whether anti-virus software deletes or isolates some files.

The last article tells me:
It may be a matter of killing software or firewall, so they are all shut down and the problem persists.
Check that the task manager does not have a ServU daemon and the service does not exist,
Go to computer management to start the service and find that the file cannot be found.
Go to the installation directory and check that there are fewer files than the other server. It is estimated that the soft upgrade has been deleted.
There is no way to reinstall it. It is not possible to reinstall it on the C drive, mainly to kill soft monitoring. The installation process encountered a problem. Some files were killed after being installed, and the configuration server prompts that the file could not be accessed.
Install it in the security zone to exclude soft scanning. Solve the problem.
Normal service needs:
Ensure that the software is correct (mainly serial numbers and file integrity)
Ensure process and service are normal
Make sure that the firewall allows communication and opens relevant ports
Prevents false positives. (In the security area, exclude monitoring and scanning)
