Why Does My Gmail Say No Connection

You may be experiencing no connection to Gmail if you’re using cellular data on your mobile device. If you’re using cellular data, you may notice that you don’t get data connection in certain areas. A secure network access point may block important ports required by Gmail if you are on one.

Gmail Temporary

Send and receive emails with Gmail Temp Mail, a temporary email account. It is easy to set up a Google Account for Gmail Temp Mail if you do not have your regular email address and need to send a message. In addition to testing messages before sending them to your regular address, Gmail Temp can be used to test your messages.

Gmail Errors

When Gmail doesn’t load, sync, log in, or fill in, users often try to re-login to their account, check their Wi-Fi connection, or other troubleshooting strategies to resolve the issue.

This may also mean that you have reached Gmail’s daily sending limit. You may be sending from multiple aliases, using multiple add-ons to send emails, or using IMAP or POP email clients.

If you already use a third-party antivirus solution, this method is usually preferable. You should be able to send your email to its destination without any problems by using Chrome or Opera. Try sending the same emails that you were unable to send using the Gmail web app.

Compose a new message

You should try to copy the same text you wanted to send and send it with the message you just composed. There are many cases where Gmail cannot properly configure itself and access its servers. In this case, try checking your Internet connection. If you are using a proxy server, try connecting to the Internet with such restrictions. Also, copy all the text (contained in the email you are trying to send), compose a new email, paste the text and try sending it to the recipient again.

Afterwards, your Gmail server should no longer display error messages once you’ve cleared the cache.
