Answer 1

The first step is to make sure your mongo service starts normally. The test method is to use local telnet on the server where mongo is located. Troubleshoot mongo service issues

If the first step is successful, switch to the same network segment telnet and test. If it cannot be accessed, check whether the port occupied by mongo is blocked by the firewall or anti-virus software. If so, add the corresponding inbound and outbound rules in the inbound and outbound rules. Troubleshoot firewall and antivirus issues.

Finally use your mongovue.

Answer 2

For Database, you need to fill in the name of the database you want to connect to, and then test the connection to see if it can pass the connection test. . .

Answer 3

『Unable to connect because the target computer actively refused. 127.0.0.1:27017』

Has it bind_ip reached 127.0.0.1?
