[OpenXPKI-users] Error after system update Debian 10

[Sandy C. <sa...@gm...>]

Hello,

I just built Openxpki with sampleconfig and it works fine for experiment
and stuff and learning about the basic functionality with the RPC API.
But then my Debian asked about OS updates and I thought that it may not
break everything.
After updating and my VM restarted, i cannot run any openxpki services like
the Web give me this error: "Backend service is not reachable or not
responding" and the RPC api give me this error:
{
    "error": {
        "message": "Unable to query OpenAPI specification from OpenXPKI
server",
        "code": 50004,
        "data": {
            "pid": 1987
        }
    }
}

And when i try to do some command like openxpkictl start and also other
commands i got this same error message:
2021/05/03 10:52:09 I18N_OPENXPKI_CLIENT_INIT_CONNECTION_FAILED; __ERROR__

How should i fix it?

Thankyou.
