Let’s look at the reasons for error 503 – Service Temporarily Unavailable for Magneto 2,

During the installation of Magento 2, the system creates the file .maintenance.flag  to show the system is under maintenance mode. This can be helpful to hide any issues or problems that occur during the installation or upgrade of your visitors.

The file is automatically removed after the overall processing is complete. But sometimes it may not be automatically removed or deleted, or the file may be created again in the system. Therefore, the existence of .maintenance.flag file in Magento 2 system will display error 503 – Service Temporarily Unavailable.

Let’s look at how to fix this error in Magento 2?

In Magento 2 root folder of var, navigate and find the file named .maintenance.flag. Delete this file. The file should have been deleted after update or installation is over, but due to some reason, it may be created again in the system.

Disabling the maintenance mode:

• First of all, go to the Magento root folder and delete the file var/.maintenance.flag.
• Then refresh magento 2 cache from php bin/magento cache: flush or via the admin panel.
• Check the error log if the message is saying “Exception printing is disabled by default for security reasons.”
• Run php bin/Magento setup: upgrade from the root directory, in case of an error says “Please Upgrade your database.”

So this was it for the day. Once you complete the above steps, you will be free from error 503 – Service temporarily Unavailable. If you face any issues while doing so, then contact our support team for help.

One important note:

The maintenance mode file in Magento 2 differs from Magento 1 in a leading dot, compare: .maintenance. Flag and maintenance. Flag!
