Error enabling local base

The local database on my server has stopped working. What could be the problem?

Please share the log. The status code is not sufficient for reliable diagnostic.

Hi @Ivan_Ermolaev and welcome in the MongoDB Community :muscle: !

Could you also please share the /etc/mongod.conf as well just in case.
If you are using the default one, please double check that you have a /data/db folder owned by root and nothing else running on the port 27017.
