The first step is to determine whether your mongo service starts normally. The test method is local to the server where mongo is locatedtelnetTesting. Eliminate mongo Service Issues

If the first step holds, replace it with the same network segmenttelnetTesting. If it cannot be accessed, check whether the port occupied by mongo is blocked by firewall or kill software. If yes, add the corresponding rules of entry and exit in the rules of entry and exit. Eliminate firewall and kill soft problems.

Finally, use your mongovue.
