• Plesk IP access policy is configured at Plesk > Tools & Settings > Restrict Administrative Access on the target server.
  \

Cause

The target server is not accessible by Plesk API locally. Plesk is configured denied connection from other networks.

Resolution

From Plesk:

1. Log into Plesk (target);

2. Check if Plesk is configured to deny connection from other networks: Plesk->Tools & Settings > IP Access Restriction Management (under “Security”) > Settings->Denied from the networks that are not listed. If it is enabled, follow step 3.

3. Add target IP to allowed IPs: Plesk-> Tools & Settings > IP Access Restriction Management (under “Security”) > Settings > select > Add Network > add the IP address of the target server.

From SSH:

1. Connect to the target via SSH;

2. Create a dump of the Plesk database:

3. Access to Plesk database:

   # plesk db

4. Add IP address of the target server to the list of allowed IP addresses:

   mysql> insert into cp_access (type, netaddr, netmask) values ('deny' , '203.0.113.2', '255.255.255.255');

   • where 203.0.113.2 - IP address of the target server.
