`DockerFacetUtils - Could not parse error response Unexpected character ('<' (code 60))`

No problem on the command line doing a docker login & pull.  
But when I try to set up a remote docker proxy repo to _remote.docker.repo_ in Nexus, I can’t seem to get it working. I am using Username Authentication, as the remote repo requires it.

command line

```auto
$ docker login remote.docker.repo
Username: prod/LOTS-OF-WORDS-HERE_WW@DOMAIN.COM
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.

Login Succeeded

$ docker pull remote.docker.repo/prod/another-namespace-here/payment:3.34
Trying to pull repository remote.docker.repo/prod/another-namespace-here/payment ...

Status: Downloaded newer image for remote.docker.repo/prod/another-namespace-here/payment:3.34

```

Seems like I may be running into [NEXUS-18263](https://issues.sonatype.org/browse/NEXUS-18263) not sure. I do not have access to the remote repo to make any config changes and I’ve tried all kinds of permutations in the remote storage url field.

Here is the logging when I try to pull the image through the proxy using a command like: _docker pull my.nexus.server/prod/another-namespace-here/payment:3.34_

```

Not sure if the problem is with my auth OR the Unexpected character error OR other.

Thanks for any assistance.

Figured out our issue. Network.

We had to add the remote hostname to **Hosts to Exclude from HTTP/HPPTS Proxy** in the System \> HTTP settings of Nexus (which was running inside a container)

The Unexpected character error was a red herring.
