I faced the same problem a few days back and resolved it after 2 hours of constant effort. In this article, I will undergo every possible way that is capable of solving the Yahoo mail server error.

So, tag along!

Why Does the Yahoo Mail Internal Server Error Occur?

The primary reason for this error is the problem with your mail account, an older app version, and a faulty internet connection. There are also some issues like two-step verification, the inaccurate configuration of POP/IMAP, and wrong DNS settings, which can cause these errors.

It can be a bit of a hassle to find out all the problems at once. So, I did some research and tracked down all the reasons.

Here are the reasons why Yahoo mail internal server error occurs:

Mail account issue

Sometimes your mail has incorrect settings, creating a faulty connection between the server and the mail. For this reason, this server error can occur.

Older version of the App

Many bugs and errors can be found in any older app version. For these bugs, the old version of the Yahoo app can not connect to the updated version of the server.

Two-step verification issue

Yahoo mail has a two-step verification option to increase its security. But sometimes, Two-Factor Authentication does not allow your mail to connect to the server, which can also cause this error.

Inaccurate Configuration of POP/IMAP

For the wrong configuration of POP/IMAP settings, the data of your hard drive saved by the Yahoo app is corrupted, which can cause this server error.

How to Fix Yahoo Mail Internal Server Error

Re-login to your Yahoo account, use the latest version of the Yahoo app, clear the cache, and establish a stable internet connection to fix the problem.

Some fixes include proper configuration of POP/IMAP, disabling two-step verification, and correct DNS settings, which can fix the Yahoo server error.

Well, for me, these fixes work like a charm. So, I suggest you go through the working solutions below.

Here are the methods to fix Yahoo mail internal server error:

1. Re-login to Yahoo Account

Sometimes Yahoo accounts leave corrupt or incorrect residue on the mail server. Re-login to your Yahoo account can refresh the mail server and remove the residue causing the error.

Here are the steps to re-login to your Yahoo account:

  • Open any Browser from your preferred device.
  • Log in to your Yahoo email account.
  • Log out from your Email account.log-out-from-your-email-account

These steps will solve Yahoo mail’s internal server issue; if it isn’t, follow the solutions below.

2. Disable Two-Factor Authentication

Sometimes Two-Factor Authentication does not allow your Yahoo mail server to function correctly for security reasons. You can fix this issue by turning it off.

Here’s how to disable two-factor authentication:  

  • Log into your Yahoo account from your preferred device.
  • Tap the upper right corner icon and select Manage your Yahoo Account.
  • Click on the Security option from the top.
  • Click Signing in to Yahoo and tap 2-Step Verification.
  • Tap the Turn Off button.Yahoo-two-factor-disable
Important Note: Yahoo Two-Factor Authentication is a safety measure to stop your email address from getting stolen. So, it will be a security threat to you if you have to turn it off. After the current problem is resolved, consider enabling the two-factor authentication again.

3. Reconfigure POP/IMAP Configuration

You must ensure that the email application is constructed with the correct Yahoo mail POP and IMAP settings. If these settings are not done correctly, the data of your hard drive saved by the Yahoo app corrupts, which can cause this server error.

This error can be solved by correctly configuring POP/IMAP settings.

Here are the steps to reconfigure POP/IMAP configuration:

  • Insert the correct IMAP configuration information.
  • Write mail.Yahoo.com into the Incoming server.
  • Enter port number 993.
  • Write mail.Yahoo.com into the outgoing server.
  • Give port number 587
  • Enter the login button.
  • Select Yes for password authentication.

4. Use The Right DNA Settings

If your DNA settings are wrong, it can create an issue between the Yahoo mail and the Yahoo mail server. Using the suitable DNA settings will solve internal server errors.

Here are the steps to use the proper DNA settings: 

  • Open Yahoo mail from your preferred device.
  • Go to Business Control Panel.
  • Click Advanced DNS Settings from the control panel.advanced-dns-settings-yahoo
  • Clear local DNS Cache and allow the IP address to be detected.

This process will automatically set the correct DNS settings for you.

5. Delete Cache

The application produces a dump file or cache when you are using the app for a long time. These dump files can create unnecessary issues in the app, which lead to an unresponsive connection between the mail application and the mail server.

Deleting the cache or dump file will solve the internal server issue.

Here is the quickest way to delete the cache: 

  • Log out from your Yahoo mail application from all devices.
  • Open you’ve preferred Browser if you want to clean the cache.
  • Click on the Three-dot icon from the top right corner to open Settings.
  • Select More Tools from settings.
  • Open the Clear Browsing Data tab from more tools.clear-browsing-data-top
  • Clear Cache from browsing data tab.
