Comment:

 Hi @yarisyaris, welcome to WordPress Trac!

 The error message means that the site could not connect to itself to run
 database upgrade routines. This generally happens when the server is not
 configured to allow loopback connections.

 You can verify if that's the case using the Health Check plugin:
 https://make.wordpress.org/support/handbook/appendix/troubleshooting-
 using-the-health-check/

 Since this appears to be an issue with a particular environment rather
 than a bug in WordPress core, please try the support forums for further
 troubleshooting: https://wordpress.org/support/.
