How to correctly index a remote DB through Sphinxsearch?

Question

Sphinx

There is a shared hosting with a spinning store based on Bitrix.
There is a VDS server with Centos 6 spinning on it, and a running sphinx.
At the moment, all the tinsel is working, but with one problem, the Bitrix database is not indexed. There are no problems in the logs. If you search on the site, then an entry appears in the query log of the sphinx, but since the index is empty, it does not find anything.
When re-indexing, it gives the following:

Success: Sphinx 2.1.9-id64-release (rel21-r4761)

If he could not connect to the database, should he write an error?
If it shouldn't, then how do you know it connects/not?
There are several million records in the database.

Are you reindexing via indexer --all --rotate ? Your output shows that it indexed 0 documents, it is logical that the index is empty.
Set up a normal sphinx is simple.
