Sharepoint foundation 2013 : After doing backup cannot access the site "Sorry, this site hasn't been shared with you"

Question

I am using SharePoint Foundation 2013 , i have backed up the site using powershell with the following command:
-backup-spsite -identity http://dmsserver/sites/demo/ -path C:\SPSiteBackup.bak
After backup finished, i can't access the site, the message "Sorry, this site hasn't been shared with you" appears, even the site administrator collection is configured coorectly, with the  Administrator account.
Whats the problem?

Hi husseinsa,
According to your description, my understanding is that you could not access the site after backing up the site collection in SharePoint 2013 Foundation.
Could you access other sites at the same site collection?
Let’s do a troubleshooting for this issue:
Please delete the IE cache:  IE options->General->Delete, select all checkboxes, and click Delete.
Go to CA->Application Management->Manage web applications, select the web application which hosts the problematic site .
Click Permisson Policy, make sure there are not any deny policies for site collection administrator and site collection auditor.
Back to the web application list page, click User Policy, check whether there are any user policies for denying permissions.
Change the site collection administrator or add a secondary site collection administrator in CA, then use the new site collection administrator to log in the site, compare the result.
Open IIS, expand the server, and click application pools.
Find the problematic web application pool, make the identity of the pool is correct, then do an IISRESET, compare the result.
If this issue still exists, please check the log file to find more information about this issue. The path of the log file is
: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS.
Or you can use Event Viewer(Start->Run->event viewer) to find the log.
I hope this helps.
Thanks,
Wendy
