Readiness Check - Magento 2.3.1

[danny_huls]

Hello,

I have a problem when i try to install a language pack on my (fresh) installed Magento. As soon as i start with the readiness check it gives a error (see also picture underneath):

Check Component Dependency
We found conflicting component dependencies. Hide detail

Command "require" failed: 
In RemoteFilesystem.php line 555:

I'm hosting on a webhost so i have no access to the php.ini. The maximum memory i can give is 768mb. PHP Version 7.1 I'm using a self signed certificate by let's encrypt. 

I tried very much to solve this error, but till now, nothing worked. 

Any solutions?

When i tried updating to 2.3.1 MAgento kept on failing the readiness check. The issue was something server side that only the support staff could change so I would start by contacting them. 

If it fails again then its a bug and probably worth reporting on the github page.

Did you manage to get this sorted? And if yes, how?

I am having exactly the same issue, pretty big chance we have the same host "versio.nl" ? 

Contacted the Helpdesk, and got this as a response: 

Ik heb in de composer.json (welke in de public_html map staat)  een aanpassing gemaakt en het volgende toegevoegd.

"config": {
"disable-tls": true,
"secure-http": false
} 
}

(he updated composer.json by adding the "config" ) 

However this resulted in a way shorter error message:
