Netease email shows that the attachment Upload Failed. Please try again! (Error code: fr_invalid_request) Solution

Recently, some computers in the Organization had a problem using Netease mail: The attachment was stuck during the upload process, and finally the prompt was given:

 

Please try again! (Error code: fr_invalid_request)

 

The computers in the Organization are all in one domain network and share the Internet through the same line. Why are some computers so awkward?

 

After research, we found that the faulty computer has a common feature: 360 guard is installed. However, after the real-time protection of 360 guard is disabled, the problem is not solved.

 

I reinstalled the faulty computer to the Windows system and started to work normally. After installing some other software, I encountered another problem.

 

You can't reload the system every time. Repeat the experiment and find a method that works.

 

Close all IE Windows, go to control panel, open Internet Options, and find the always send URL with UTF-8 option in settings on the Advanced tab, if it was originally hooked, It would be canceled. If it was not hooked, It would be hooked. OK. Save the settings.

 

There is another unconfirmed method:

 

After entering the mailbox, modify the mailbox parameter settings and set the "post-mail, sent mail:" item to not save.

 

The following methods seem useless:

 

1. Delete cookies and temporary files of IE

 

Open the Internet option, delete Temporary Internet Files and cookies on the "General" tab, save and confirm.

 

2. Reduce the security level.

 

Turn on the Internet option and set the security level to moderate on the Security tab.

 

3. Disable third-party add-ons.

 

Open the Internet option. On the "program" tab, click "Manage Add-ons" to add all third-party add-ons that are not included in windows.

 

4. Reset the iesettings.

 

Enable the Internet option. On the "advanced" tab, click "reset ".

 

5. Disable or disable Real-time protection for anti-virus software and firewall software.

 

6. Install IE7 or IE8.

 

7. Select "simple style" when logging on to your mailbox ".
