"curl_version" from namespace "Stripe\HttpClient"

[Hightmar]

Hello everyone,

I obviously have a problem with cURL that makes my server crash (error 500) when I want to configure Stripe and/or Paypal. My /order page displays a 500 error too. I've never had this problem before and I don't understand what's going on. 

I'm on :
PrestaShop 1.7.6.4
PHP FPM 7.2.28
cURL :

curl 7.64.0 (x86_64-pc-linux-gnu) libcurl/7.64.0 OpenSSL/1.1.1d zlib/1.2.11 libidn2/2.2.0 libpsl/0.20.2 (+libidn2/2.0.5) libssh2/1.8.0 nghttp2/1.36.0 librtmp/2.3
Release-Date: 2019-02-06

I get the following error messages:

Stripe :

Do you have any resolution ideas?
