paypal does not work

[arctanh]

I have set up 2 websites (with different domains),

now when I try to buy something and I click "Continue to PayPal" the rotating wheel appears and nothing happens. Just loads forever.

Pls. give me advice. I've been trying different options for 3 days now and nothing works

Thanks! I have created a new test M2 store (no multisite) and still does not work.

This is what I get in the console:

jquery-migrate.js:41 JQMIGRATE: jQuery.browser is deprecated

jquery.js:9666 PUT http://...mysite.../rest/default/V1/guest-carts/e1342da078ab3add30a7e25dc5a82728/selected-payment-method net::ERR_EMPTY_RESPONSE

send @ jquery.js:9666jQuery.extend.ajax @ jquery.js:9211
put @ storage.js:59
(anonymous function) @ set-payment-method.js:43
Component.extend.continueToPayPal @ paypal-express-abstract.js:76
(anonymous function) @ knockout.js:3863
jQuery.event.dispatch @ jquery.js:4624
elemData.handle @ jquery.js:4292

VM5789:1 Uncaught SyntaxError: Unexpected end of input

fire @jquery.js:3099
self.fireWith @jquery.js:3211
done @jquery.js:9312
callback @jquery.js:9720

any ideas what is wrong?

on github there are also other users with this problem.

i would really appreaciate a fix or some ideas how to debug. it's hard to run a store where no payments can be made

Hi there,

Can you please provide more details about the problem because we have integerated the paypal on our website  and mobile app  and  it is working fine. For reference you can look at our website (http://magento22.ipragmatech.com/) and mobile app(http://www.ipragmatech.com/products/android-magento-mobile-app/)
