Comment 1 for bug 1993618

It appears that the problem comes from these redirects in regiond.nginx.conf:

```

    location = / {
        return 301 /MAAS/r/;
    }

    location ~ ^/MAAS/?$ {
        return 301 /MAAS/r/;
    }
```

A potential fix could be to turn off absolute redirects, so that redirects will be automatically interpreted in the context of the requesting url:

```
diff --git a/src/maasserver/templates/http/regiond.nginx.conf.template b/src/maasserver/templates/http/regiond.nginx.conf.template
index b45a7fff9..d9593ccc9 100644

```
