MRT为企业互联网+ 赋能

When we are building a website, we inevitably encounter some problems, such as the most common problem of not being able to open the website. After the completion of construction, many websites experience situations where users are unable to access them, web pages cannot be opened, and even network paralysis. Faced with such a problem, we need to find the problem and apply the right medicine to it! Below, Guangzhou Mingruixundong Company will take everyone to take a look at common website construction issues and their solutions that cannot be opened!

1、 Network conditions are troubled

1. Local network connectivity issues

Solution: When you are unable to browse a website, first check if other websites can be accessed normally. If the problem persists, you can call the customer service hotline of your local network service provider, such as Unicom customer service hotline: 10010; Telecom customer service hotline: 10000; Tietong customer service hotline: 10050; Mobile customer service hotline: 10086.

2. Local firewall or gateway settings

Solution: Check the local firewall blacklist to see if there are any domain names that want to open the website. If any, delete it; If it is a gateway issue, log in to the router, restore factory settings, and restart.

3. Domain name resolution blocked

Solution: Click on the "Start Menu", select "Run", type "CMD", confirm, and then type ping your domain name (please leave a space in the middle). If the return value is "Request timed out", that is, if the domain name resolution fails, contact the domain name registrar for resolution; If the return value has an IP address, or if there is a problem with the server or computer room, refer to the response method for "Computer Room or Server Problem".

2、 Internal issues with the website

1. The homepage file name does not match

Countermeasures: The default homepage of websites is commonly referred to as index. html, index. htm, index. aspx, index. aspx, default. htm, default. aspx, index. php, and default. php. Check if the website root directory stores the above files.

2. Missing or removing necessary files from the website

Countermeasures: Failure to upload website files or improper FTP operation to delete website homepage files and database link files may result in inaccessible websites. Log in to the website FTP and check if the necessary files are present, or upload them again (be sure to backup new data).

3. The website is under attack

Countermeasures: The website is vulnerable to security vulnerabilities, being attacked by hackers and tampering with necessary website files. At that time, we can only contact the website construction company to solve such problems.

4. Site script program execution error (such as inability to connect to database), resulting in page display obstruction

Countermeasure: Usually, this situation will display specific error messages on the access page, and the program can be checked based on this information.

3、 Machine room or server issues

1. Excessive website traffic

Summary of reasons: Although most virtual hosts no longer restrict traffic, if a website provides a large amount of downloads or consumes server resources, IDC service providers may pay attention to the website's situation.

2. The server is experiencing downtime

Reason Overview: During the operation of the server, it is inevitable to suffer from downtime, which is only a matter of probability. Sometimes it's an IIS issue, sometimes it's a server system issue.

3. Server security vulnerabilities, vulnerable to attacks

Summary of reasons: There are no servers that are absolutely safe, as there are people outside of us and heaven outside of us. The server being attacked by hackers is also the reason why websites cannot be accessed.

4. The computer room is under attack

Reason Overview: The types of attacks encountered by computer rooms are generally DoS/DDoS attacks or ARP attacks, which may affect specific IP address segments (such as 123.134.32. X). When attacked, the IP segment website may be slow or difficult to open.

5. Filing issues

Summary of reasons: Since 2009, filing issues have become the latest cause of website inability to access. The presence of unregistered websites or illegal information on websites or their servers may lead to website or server downtime.

Solution: If there is a problem with the computer room or server, please contact the virtual host service provider or computer room to provide corresponding solutions.

The above are common issues and solutions that may arise when building a website that cannot be opened. When we encounter website issues that cannot be opened, we can troubleshoot them through network issues, website issues, as well as computer room or server issues, and provide targeted solutions to restore the website to normal operation.
