@AhmedTarek123 This is a connection time out issue - please check for the obvious like content directory path, URL and folder permissions. Also looks like you are trying to have an HA setup - what is the ArcGIS version? Check references below:

Hello @AhmedTarek123 

It seems like when the configuration wizard is trying to reach the internal Database, it is unable to achieve a response in designed time.

I would suggest having a look at the following documentation and running a check for these on the Data Store machines (in your scenario Relational Data Store):

Ports used by ArcGIS Data Store 

Mostly, as per my understanding it could be 9876 port:

• 9876 (TCP)—Internal communication between the hosting ArcGIS Server site and the relational data store occurs through this port, as does some communication between the primary and standby relational data store machines.

Furthermore, I would recommend adding an exception to Windows Firewall as disabling the Firewall would a tricky situation with IT team.

This explains those steps in details : Adding Windows Firewall Exceptions   

Hope it helps!

Greetings @AhmedTarek123 

When configuring the Data Store through the Wizard as per the image you supplied, I would recommend trying to use the FQDN of the server instead of "localhost".  For instance, if this is a base deployment (all components in the same machine, try https://lp-3-3-31.esri.local:2443/arcgis/datastore. 

Hope that helps.
