No connection to local databases

[j08ur]

I have PostgreSQL and Clickhouse databases running on a server. Both are accessible via DBeaver or via http
But when I try to make a connection in Datalens, connection attempt fails, with the error like this(for clickhouse):
Data source refused connection. ERR.DS_API.DB.SOURCE_CONNECT_ERROR { "data": { "details": { "db_message": "HTTPSConnectionPool(host='192.168.1.224', port=8123): Max retries exceeded with url: /?query_id=e7c0bdde-b9f7-11ee-bdd0-0242ac120006&database=system&join_use_nulls=1&distributed_ddl_task_timeout=280&send_progress_in_http_headers=0&output_format_json_quote_denormals=1 (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f43f6287130>, 'Connection to 192.168.1.224 timed out. (connect timeout=1.0)'))" }, "message": "Data source refused connection.", "debug": { "db_message": "HTTPSConnectionPool(host='192.168.1.224', port=8123): Max retries exceeded with url: /?query_id=e7c0bdde-b9f7-11ee-bdd0-0242ac120006&database=system&join_use_nulls=1&distributed_ddl_task_timeout=280&send_progress_in_http_headers=0&output_format_json_quote_denormals=1 (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x7f43f6287130>, 'Connection to 192.168.1.224 timed out. (connect timeout=1.0)'))", "query": "select 1" }, "code": "ERR.DS_API.DB.SOURCE_CONNECT_ERROR" } }
The same problem appears while running Datalens container on the server or on the other machine in network.

Could you please tell me, what may be the issue?

Hi! connect timeout=1.0 means DataLens cannot connect to your PostgreSQL/ClickHouse. This can be caused by a multitude of reasons, for example, if your DB is not reachable from your docker container.

You can check it by connecting to the data-api container using docker exec -it <container id> bash and querying the DB from it (for example, with ClickHouse's http interface ).

If that is not the case, please let us know where your DBs are deployed (e.g. locally on the same host as DataLens or on another remote one) and how do you connect to them via dbeaver/http
