This is the blockchain height at that server, so it is working.

I don't see that you have any problem except that the server is down and
the configuration file is not located. If you call:

$ bx fetch-height -c bx.cfg

The default path for the process is used. If you call:

$ bx fetch-height

The file 'bx.cfg' in the installed location is used. Use the command:

$ bx settings

to determine if your configuration file is actually being used.

You may also specify the server directly on the `fetch-height` command
(only). This will override the server in the configuration file or the
default as the case may be.
