I am trying to migrate into DevKinsta with Duplicator.

Duplicator cannot connect to database:

> Unable to connect the user **[root]** to the host **[127.0.0.1]**. The server error response was: _Connection refused_

> [PHP ERR][WARN] MSG:chmod(): Operation not permitted [CODE:2|FILE:/www/kinsta/public/xxx/dup-installer/lib/snaplib/class.snaplib.u.io.php|LINE:600]  
> Permissions setting on file ‘/www/kinsta/public/xxx/installer.php’ failed

> [PHP ERR][WARN] MSG:chmod(): Operation not permitted [CODE:2|FILE:/www/kinsta/public/xxx/dup-installer/lib/snaplib/class.snaplib.u.io.php|LINE:600]  
> Permissions setting on file ‘/www/kinsta/public/xxx/to\_local\_2\_[HASH]\_20210301160645\_archive.zip’ failed

I wonder if the database port my the issue here. Because Duplicator has not way (that I know of) to define the port. Duplicator docs do not mention any issues here at all.

Any ideas?

Ok, found the solution.

In Duplicator for database host, **do not use “127.0.0.1”** from DevKinsta dashboard

but **do use “devkinsta\_db”** from wp-config
