I have installed Coinpayment with https://github.com/hexters/CoinPayment inside mine project.
The problem what i;m getting is Coinpayments can't send IPN request to mine server or there is somewhere timeout. Now i have try all option and try to reinstall i'm not getting success to solve this problem.
Here is the picture what i'm getting in Coinpayments
ENV file
COINPAYMENT_PUBLIC_KEY=x
COINPAYMENT_PRIVATE_KEY=x
COINPAYMENT_CURRENCY=EUR
COINPAYMENT_IPN_ACTIVATE=true
COINPAYMENT_MARCHANT_ID=x
COINPAYMENT_IPN_SECRET=x
COINPAYMENT_IPN_DEBUG_EMAIL=x
I have also add the path for Except in App\Http\Middleware\VerifyCsrfToken
protected $except = [
'/coinpayment/ipn',
];
Can anyone help me to solve this problem?

at first you need to know that coinpayment/ipn adress should accessable from outside, on which hoster you have uploaded the project?
Sometimes there are firewalls around the server which makes it unuasble Can you check that? More informations you can find in the check the Webserver access-Logfiles.
Sometimes there are Status 502 (Bad Gateway) or HTTP-Status 503 errors.
