Client error 404

Nobody has claimed this yet.

Not sure what I'm doing wrong here. It's possibly more likely that I can't figure out the instructions as opposed to there actually being something wrong.

I'm following the instructions to both run the docker (version tag 1.4.1) and install it natively. Both successfully run, giving me a container of a process in the background. When I then attempt to query a bam using either of the the methods [documented here](https://htsget.readthedocs.io/en/latest/index.html), i.e:
```
htsget http://htsnexus.rnd.dnanex.us/v1/reads/BroadHiSeqX_b37/NA12878 --reference-name=2 --start=1000 --end=20000 -O NA12878_2.bam
```
I get "server returned empty JSON ticket. It's probably not meant to do that, don't know why it is, but at least it is connecting.

When I attempt to query the test data in the container or using the natively installed one, I change the url to localhost - using the port that I specified for the docker, I get:

```
htsget http://localhost:3000/data/gcp/gatk-test-data/wgs_bam --reference-name=2 --start=1000 --end=20000 -O NA12878_2.bam
/home/bcurran/bin/miniconda3/envs/ga4gh/bin/htsget: error: 404 Client Error: Not Found:404 page not found
```
I am getting this using the api and the cli, which make me think there is a piece of instruction that I am missing. I have checked the docker to make sure that there is a relevant bam file in the correct location, there is. I have tried altering the url leaving the file path out, all of which returns the same error. I assuming that for this baseline test, I do not need to specify data sources in a config file?

The error, when using the API, is slightly longer, included below in case it's useful.
```

Thanks

Reproduce the Docker 1.4.1 setup and the localhost:3000 request using the documented htsget CLI and API entry points. Check how the server exposes the referenced BAM path and whether baseline test data requires configuration; done means the documented request returns a valid ticket instead of 404.
