@Agusbou2015: Did Benjavalero explicitly agree to work on fixing this?

It's resolved! Tool now works as expected.

Aa far as I can see, the tools-db database has been unavailable for the tool. According to the logs, between 21.32 and 22.06 (UTC) of 28-Sep.

Please, if you see any inadequate use of the tool provoking this unavailability, please let me know in order to try to improve the tool.
