Plesk is not accessible: Unable to find service node for web service on domain with id=xxx

Symptoms

• When trying to log into Plesk or when trying to open a domain in dashboard, Plesk shows the following error:

  PLESK_ERROR: Internal error: Unable to find service node for web service on domain with id=111

• The command "plesk repair db" reports the following error message:

  # plesk repair db -n
  Inconsistency in the table 'domains' for the column id: No rows in the table 'DomainServices' with type = 'web', dom_id = 111 ........ [ERROR]

Cause

Inconsistency in the Plesk database.

Resolution

Note: Steps below are the same for both Linux and Windows.  

1. Connect to the Plesk server via SSH/RDP.

2. Create a dump of the Plesk database.

3. Connect to the Plesk database with the command (On Windows Server use a command prompt):

   # plesk db

4. Find the domain's "ip_address_id" using dom_id value from the error message (for example  dom_id = 111):

   MYSQL_LIN: mysql> select dom_id,param,val from dom_param where param='ip_addr_id' and dom_id=111;
   +--------+------------+------+
   | dom_id |   param    |  val |
   +--------+------------+------+
   |  111   | ip_addr_id |   1  |
   +--------+------------+------+

5. Find the "id" with the type "mail" in DomainServices:

   MYSQL_LIN: mysql> select * from DomainServices where dom_id=111;
   +------+--------+------+--------+---------------+----------------+
   | id   | dom_id | type | status | parameters_id | ipCollectionId |
   +------+--------+------+--------+---------------+----------------+
   | 25   | 111    | mail | 0      | 639           | 25             |
   +------+--------+------+--------+---------------+----------------+

6. Find "id" of the IP address assigned to the domain:

   MYSQL_LIN: mysql> select * from IpAddressesCollections where ipCollectionId=25;
   +----------------+-------------+
   | ipCollectionId | ipAddressId |
   +----------------+-------------+
   | 25             | 1           |
   +----------------+-------------+

7. Find the next free value for the "id" field in the DomainServices table: 

   MYSQL_LIN: mysql> select max(id)+1 from DomainServices;
   +-----------+
   | max(id)+1 |
   +-----------+
   | 1447      |
   +-----------+

8. Create the missing records using id from step 7 (in this example id=1447) and ipCollectionId as 1 + the value from step 6 (in this example ipCollectionId=26 [25+1]):

   • In the DomainServices table:

     MYSQL_LIN: mysql> insert into DomainServices (id, dom_id, type, status, parameters_id, ipCollectionId) values ('1447', '111', 'web', '0', '0', '26');

   • In the IpAddressesCollections table:

     MYSQL_LIN: mysql> insert into IpAddressesCollections (ipCollectionId, ipAddressId) values ('26', '1');

   • In the IpCollections table:

     MYSQL_LIN: mysql> insert into IpCollections (id) values ('26');
