This article uses easy-to-understand examples to introduce the reasons for the failure of remote links to cloud servers. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

When the remote desktop of the CVM cannot be connected, you can log in to the server for troubleshooting through the remote connection feature of the service provider console. There are many possible reasons for the failure of remote links, such as the opening of the firewall when Windows logs in for the first time, the setting of remote ports out of range, antivirus security software, and so on.

Remote port settings are out of range

Whether on Windows or Linux systems, the range of ports that can be used by service snooping is 0-65535. Misconfigured listening ports will cause remote desktop service snooping to fail. In this case, the port is re-modified to another port that is not occupied between 0 and 65535.

Antivirus security software causes

After the CVM is leased, the failure of the remote link may be caused by the setting of three-party antivirus software. For example, if the security dog blacklist is blocked, if the security dog is installed, the client cannot connect to the CVM locally and cannot ping the IP address of the server. Other regions can connect remotely. You can check whether security settings or corresponding blocking have been made in the corresponding protection software.

You can choose server security dog > network firewall. Click the rule setting of the super blacklist. If the instance public network IP exists in the blacklist, delete the blacklist rule, and then add the public network IP to the whitelist.

This is the reason for the failure of the remote link to the CVM. I hope the above content can be of some help and learn more knowledge. If you think the article is good, you can share it for more people to see.
