Please do not append port 80 or 443 when I set a custom host, as this can lead to errors on certain gateways.

\ollama_client.py, line 74, in _request
raise ResponseError(e.response.text, e.response.status_code) from None
ollama._types.ResponseError: path location is not configured.

I found that the host was appended with port 80 by the following code in the _client.py file, causing the server gateway forwarding to fail.

def _parse_host(host: Optional[str]) -> str:
  host, port = host or '', 11434
  scheme, _, hostport = host.partition('://')
  if not hostport:
    scheme, hostport = 'http', host
  elif scheme == 'http':
    port = 80
  elif scheme == 'https':
    port = 443

  split = urllib.parse.urlsplit('://'.join([scheme, hostport]))
  host = split.hostname or '127.0.0.1'
  port = split.port or port

  return f'{scheme}://{host}:{port}'

Start in _client.py at _parse_host, with the failure context from ollama_client.py line 74 and the gateway error shown in the issue. Verify how custom http and https hosts are normalized, then confirm that a custom host is not given an implicit port 80 or 443 when forwarding through the gateway.
