What is the reason why I cannot connect to the CVM? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

First, check whether there is a problem with the local network, and then go to ping to see if the Ip of the CVM can be connected with ping. If the CVM cannot be connected with ping, it means that the operation of the CVM is abnormal, and you can directly check it by contacting the operator of the server room with IP.

In general, if the server IP is blocked, we should see that most of the timeout nodes are in the PING test, but if the PING is normal, it means that the server SSH cannot connect. You can also check the reason:

1. Check whether the CVM expires. If it expires and is not renewed, it will definitely fail to open it.

two。 Check the server web system to make sure that there is no port problem, it may be a Nginx or MySQL failure in the web environment

3. Whether the CPU resource of the CVM is overloaded. If the resource consumption exceeds the configuration, it will be restricted and paused.

4. The server IP or domain name is blocked. If the content of the CVM is not allowed, it can be easily detected.

5. Official maintenance, it is also possible that the cloud service provider server problems and fault maintenance, contact the vendor to determine.

The answer to the question about the reason why you cannot connect to the CVM is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
