Magento 2 API Error

I need some help about my Magento 2 site. * Please do not offer something without read carefully.

The coupon inbox is not working on my Magento 2.2.4 site's payment page.

When i checked with Chrome's developer tool; i saw this error:

Uncaught SyntaxError: Unexpected token < in JSON at position 0

at [login to view URL] (<anonymous>)

at [login to view URL] ([login to view URL])

at Object.<anonymous> ([login to view URL])

at fire ([login to view URL])

at [login to view URL] [as rejectWith] ([login to view URL])

at done ([login to view URL])

at [login to view URL] ([login to view URL])

- there is no wrong on file permissions and chmods; i'm sure.

I re-install magento 2.2.4 and theme again to make a fresh test; but the problem is the same. (the theme owners are saying 'they are tested several times; and everything is ok at their site; and also i saw their site is working too)

I'm not sure if its a server config problem or not (i checked all topics on Stackoverflow and Google; but couldn't get the solution)

By the way; i saw this 404 error for API PUT method on chrome console at the same page:

PUT [login to view URL] 404 ()

In Network tab; i see this error ([login to view URL] is my site):

Request URL: [login to view URL]

Request Method: PUT

Status Code: 404

Remote Address: [login to view URL]

Referrer Policy: no-referrer-when-downgrade

By the way; i also saw this error in Apache logs (but not sure if its about this problem or not)

2018/06/08 20:53:29 [error] 3436#3436: *28844 upstream prematurely

closed connection while reading response header from upstream, client:

[login to view URL], server: [login to view URL], request: "GET


HTTP/1.1", upstream: "[login to view URL]

sections=cart&update_section_id=false&_=1528491190921", host:

"[login to view URL]", referrer: "[login to view URL]"

the coupon input is working in cart page page (i mean; there is no error in coupon process)

could someone help me with $20 budget?
