Error: Access for administrator from address 'XX.XX.XX.XX' is restricted in accordance with IP Access restriction policy currently applied.

Please follow the steps to resolve the issue:

1. Login to the Windows server and go the path %plesk_bin% from the command prompt.
2. You can retrieve the current policy and restricted/allowed IPs  from the following commands:

%plesk_bin%\dbclient.exe --direct-sql --sql="select * from cp_access"
OUTPUT
id      type    netaddr            netmask
1       allow   XX.X.XX.XX      255.255.255.255
2       deny    XX.X.XX.XX      255.255.255.255

%plesk_bin%\dbclient.exe --direct-sql --sql="select * from misc where param='access_policy'";
OUTPUT
param             val
access_policy   deny

3. To clear the access policy settings remove all the records from the "cp_access" table and set policy to "allow"
%plesk_bin%\dbclient.exe --direct-sql --sql="update misc set val='allow' where param='access_policy'";
