llvm dev - Sep 2021 - arc install-certificate failure

when I try to install “arc” following the “quick-start”(◉ Arcanist Quick Start
<https://secure.phabricator.com/book/phabricator/article/arcanist_quick_start/>)
everything is fine, but when I try to install-certificate I got stuck.
It gives me the following message.

```
CONNECT  Connecting to "https://reviews.llvm.org/api/"...
Usage Exception: Failed to connect to server (https://reviews.llvm.org/api/): 
Host returned HTTP/200, but invalid JSON data in response to a Conduit method
call.
```
can anyone help me? Thanks.

When I add the "--trace" options, I got the following error message:
```

After checking the source code, it seems likes “conduit.ping” method failed,
but I can not get any other clues now.
```

$uri = $this->determineConduitURI(); 54 $this->setConduitURI($uri); 55

$configuration_manager->readUserConfigurationFile(); 58 59
$this->writeInfo(
60 pht('CONNECT'), 61 pht( 62 'Connecting to "%s"...',
63 $uri)); 64 65
$conduit = $this->establishConduit()->getConduit(); 66 try { 67 $conduit
->callMethodSynchronous('conduit.ping', array()); 68 } catch
(Exception $ex)
{ 69 throw new ArcanistUsageException( 70 pht( 71 'Failed to connect to

Hello,

Maybe logon to the web interface first, then visit
https://reviews.llvm.org/conduit/login/.
You will get a page with a string beginning with "cli-".

Create ~/.arcrc like this:
```
{
  "hosts": {
    "https://reviews.llvm.org/api/": {
      "token": "cli-<rest of your token here>"
    }
  }
}
```

Then proceed as if you've completed the "install-certificate"
step. I hope
this helps.
