What Causes the Issue to Appear?
The problem is sometimes caused when users are trying to send an email from an account they have just created which hasn’t been registered by Google yet. Also, the same error can appear when trying to send a single email to multiple users. This can be a huge issue for business users who are struggling to send an important email and it’s important to handle the problem as soon as possible. Let’s check out some of the most helpful methods which have worked for users with the same problem!
Solution 1: Clear Browsing Data on Your Browser
Users were able to solve this problem when it occurred on their respective browser simply by clearing out browsing data. This data adds up over time and it can cause all kinds of errors, especially with mail credential. Check out our instructions on how to clear your browsing data (cookies and cache) on the two major browsers.
Mozilla Firefox:
Google Chrome:
Solution 2: Log out and Back into Your Gmail Account
If there was a minor issue with your account, it can be fixed simply by logging out back in since it will reset your data on the server. It’s also advisable to exit out and back into your browser just to make sure. Additionally, simply restarting the browser has worked for some users whereas others also needed to log into their Gmail account.
Solution 3: Uninstall Google Earth
Because of a bug in Google Earth, if you were trying to send a mail using a browser installed on your computer or the mail client on Windows 10, you might want to try and uninstall Google Earth and check to see if the problem still appears. The correlation between these things seems unnatural but it’s worth checking this out as you can redownload Google Earth quite easily.
Solution 4: Add Exception for Google Servers for AVG
AVG is a free antivirus tool which does its job quite well but it has been reported that it caused this error to occur when trying to send a mail using Gmail. Users have tried disabling all AVG shields for a while and the error stopped occurring. However, disabling antivirus shields is not a good permanent solution as your PC stays unprotected. Instead, you can allow Google server traffic through AVG.
