400-bad Request failed requests error (one of the most common errors)
The problem is that the URL you typed is faulty. It is possible that the server you are connecting to does not recognize the document you are requesting to browse, or that you do not have access to it or even that it simply does not exist. Carefully check whether you write the URL wrong, including the case (general URL is not case-sensitive, but some special document exceptions), symbols or more dozen spaces. This is the most common type of error.

401-unauthorized not certified Error

You may have access to a password-protected site and you have entered a password that is incorrect. First you need to verify that you have access to the site (usually with a username and password), that the password is strictly case-sensitive, and generally not anonymous.

403-forbidden Prohibit access errors

You may not have the right to access this document, sometimes some pages are not allowed to access directly (no link to the above page), of course, there is the possibility of password protection. Then you need to go back to the previous page and enter the password before you can access it.

404-not found did not find the error (most common error bis)

This is the access error that we often encounter. First of all, it may be that your URL has errors (missing words, case, symbol differences, etc.), or the end of the URL extension is not correct, of course, there may be this address or the page does not exist.

425-can ' t Open data connection the connection failed

This is typically caused by a server passive mode port that is not open or occupied, checking for other programs and whether the firewall is open to the (series) port.

500-server Error Server errors

Usually it is the other side of the Web page design error, may be modified and uploaded pages, waiting for the other page to correct the error and then try again.

503-service Unavailable Service Unavailable error (common error three)

There are many possibilities: Your ISP server crashes, your company's gateway is broken (if you're using a unit's LAN), or your own system has a problem. The best way is to wait and try again, if you still do not go to see your machine, ask the network administrator.

Bad file request error files requests

Your browser requires access to special forms of files and documents, such as data fields and Drop-down lists, but the pages you visit do not have these forms, or you have errors in the form. You only have to notify the administrator to update the form.

Socks Error proxy Server (common error four)

This is the most common error on a client computer in a proxy environment because of a connection timeout, a proxy server has been turned off, or the connection has been disconnected. Consult the server administrator to find the appropriate error and resolve it against.

Request Time Out Connection Timeout error (common error five)

Connection timeout, the main reason may be your network speed is too bad, or you set the timeout in the browser option, or because of the server problem, try more.

An unexpected web error occurred unpredictable web page errors

There are many reasons for this error and there are no detailed explanations and solutions. Only use the above mentioned step by step access to the parent directory, or give up.

Cannot add form submission result to Bookmark list cannot form knot
Add Bookmark list

When you search for a bunch of URLs and want to save the results to a bookmark, you may not be able to add it to a bookmark because you get a Dynamic Web page. You can save the results page as an HTML file on your hard drive.

Failed DNS Lookup DNS lookup failure error

DNS (domain Name System) is used to translate the URL into a legitimate Internet physical address, this error may be you enter the address error, check the loss
Address, and then try again.

file contains no data file no content error

The site you visit is correct, but there is no Web page, only try several times to see.

Connection refused by host hosts deny connection

It may be that you have no access to the site, or that it denies access to your IP (or IP segment) or that it may be password-protected.

Viewer not found unable to find viewers error

There are a variety of files on the web, such as sound files, compressed files, animation files. If your browser does not define the relevant software, you will not be able to access it. The simple solution is to download and install the relevant software.

Unable to locate cannot locate server errors

You may have entered a problem with the URL, or the server does not exist, or the server has been canceled (at this point, there will be a page prompts you to go to the corresponding page). Re-check the address you entered and try again.

Host unavailable hosts are not available for errors

It is possible that the host crashed. Wait a moment, refresh and look again.

Network connection was refused the server denied network connection error

There are too many users requesting access to the A, and cannot answer your request. Just keep on refreshing and try again.

Ii. common errors and resolutions in FTP, newsgroups, foxmail and oe, cuteftp, netants

Not connet,access deny deny connection access error

Cannot login and access anonymously, you must provide a username and password to log in. You only have to apply for a username to get into the mainframe.

Bad target URL destination URL error

The most common mistake in using the network ant netants is that your job has a problem with the URL address, you may have a problem with your input, or you may have a connection error on the server.

Too Many users too many

The error that occurs when you log on to FTP. This is due to too many users accessing the FTP site, so you can try it in a different time period.

Can ' t log on as a anonymous user you cannot log on as anonymous

Some FTP sites allow access through anonymity (that is, by using a anonymous username and password), but some only allow their members (with specific user names and passwords) to access them. Another possibility is that your browser does not support anonymous FTP access, and you can access it using specialized FTP software such as CuteFTP.

Permission denied denied access

When you try to upload a file to an FTP site, there is no permission or the site is too busy.

The NNTP server error newsgroup server error

When you try to log in to a news discussion group, the error may be caused by a server shutdown or a disconnected connection.

Too many connections--try again later too many connections, wait a second and try again.
This is also due to the user too much error message, you have another time to visit it!

The Receive and send data error received or sent errors

When using Foxmail or Outlook Express, the connection to the server is accidentally interrupted due to poor line quality.

When you use Foxmail or Outlook Express, you cannot connect to your mail server. Please check that you are connected to your ISP or that the network is disconnected, and this can happen if the mail server is turned off or too busy.

Can ' t resolve server address cannot resolve

When using Foxmail or Outlook Express, resolving server addresses fails, usually because the DNS server is not connected, or the POP3 (SMTP) server name is incorrectly written, and the server setting parameters for the mailbox are corrected.

The actual size of downloading file is unknown download size cannot be determined

This is a bug for netants because netants must know the size of the file before downloading the file because the server's answer does not include the file size. will be improved in later versions.

Warning the server says 553 sorry,that domain isn ' t in my list of allowed send mailbox address error

The error that occurs when you use Outlook Express and Foxmail is that the SMTP server does not accept the e-mail address you are sending. Typically, some free mail servers only accept e-mail addresses that are sent to it. Workaround: Replace an SMTP server address. [Page]
