Service Temporarily Unavailable in Magento 1

You should check if there is a file maintenance.flag in Magento root folder.

Why?

During installation process, Magento creates the file maintenance.flag, if Magento checks that file exists, and it will show to users the error messsage as I showed above. Generally, it will automatically remove maintenance.flag file after the processing has been done, but there are something went wrong and you cannot delete it.

Solution

Delete the file maintenance.flag in Magento root folder.

Service Temporarily Unavailable in Magento 2

It is very similar with Magento 1. The file now is .maintenance.flag not maintenance.flag. There is a dot at the begining of the file.

Solution

• Delete a file called var/.maintenance.flag in the Magento root folder
• Remove Magento cache if there is any: php bin/magento cache:flush
