SSH acess blocked after user was added to sftp group

Question

I have a specific user and group associated to an SFTP service in my server.

recently I added my regular group to the group associated with the SFTP, and now I can no longer connect to the server via SSH. I get this message:

Could not chdir to home directory /home/administrador: No such file or directory
This service allows sftp connections only.

is there any work around this problem apart from physically logging in to the server and undoing the group association?

Answer 1

If you don't have any other user, who is able to log in and fix your configuration/groups over ssh, you need to log in locally (or using some web console).
