This article will provide you with a series of efficient solutions to help you get out of trouble quickly.

How to solve access denied by AliCloud server

1、 Troubleshoot network problems

First, when the server denies access, we need to confirm whether there is a problem with the network connection. You can try to ping the IP address of the server to see whether it can respond normally. If the ping fails, it may be a network failure or the server IP is blocked. At this point, you need to contact the network administrator or Alibaba Cloud customer service to confirm the network status and seek solutions.

2、 Check server status

If the network is normal, we need to further check the status of the server. Log in to the AliCloud console to view the running status, instance status, and security group settings of the server. Ensure that the server instance is running and that the security group rules allow access to your IP address. If any abnormality is found, timely adjust the server status and security group settings.

3、 Check firewall settings

The firewall settings of the server itself may also lead to access denial. After logging in to the server, check the firewall rules to ensure that the required ports have been opened. If you use Alibaba Cloud's security group function, you also need to ensure that the security group rules match the firewall rules.

4、 View logs to locate problems

If the above steps do not solve the problem, we can check the server log to locate the problem. Check the system log, application log, security log, etc. to see if there is abnormal information or error prompt. According to the log information, we can further analyze the cause of the problem and take corresponding solutions.

5、 Contact Alibaba Cloud customer service

If you still have difficulties in troubleshooting and solving problems yourself, you can contact Alibaba Cloud customer service for help. Alibaba Cloud customer service team has rich technical experience and can provide you with professional technical support and solutions. When contacting customer service, try to provide detailed problem description and relevant information so that customer service personnel can quickly locate the problem and provide solutions.

6、 Back up data just in case

In the process of solving the problem of server access denial, we also need to pay attention to data security at all times. Before any operation that may cause data loss, make sure to back up the data. In this way, even if the problem cannot be solved, we can ensure the security of data and avoid greater losses.
