Unable to process payment due to a communications error

I was getting an error when someone tries to make a credit card payment. At the point where they confirm the payment they get:
"Unable to process payment due to a communications error. You may try again or contact us for assistance"
So following suggestions on another post:
I contacted the server company and told them:
Point your hosting company to http://corsoitalianspecialties.com/extras/curltester.php and ask them to fix the server's certificate chains and OpenSSL implementation.
They said that I have to update PHP. (which I did to 7)
That did not work- called them back and they said that I have to purchase SSL for the domain.
I did that but no change. I called back and I guess they redirected all requests to the domain to https://
I don't necessarily have an issue with that, but that did not change anything.
Getting error:"This is a non-secure form.
This form will be sent in a way that is not secure. Are you sure you want to send it?" Then the user and password disappears and asks me to sign in again.
So...
I changed the server address in configure (added s for HTTPS_SERVER)
define('HTTP_SERVER', 'http://corsoitalianspecialties.com');
define('HTTPS_SERVER', 'https://corsoitalianspecialties.com');
define('ENABLE_SSL', 'true');

define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');

And the Admin config:

• Enter the domain for your Admin URL. If you have SSL, enter the correct https address in the HTTP_SERVER setting, instead of just an http address.
  /
  define('HTTP_SERVER', 'https://corsoitalianspecialties.com');
  /*
• Enter the domain for your storefront URL.
• Enter a separate SSL URL in HTTPS_CATALOG_SERVER if your store supports SSL.
  */
  define('HTTP_CATALOG_SERVER', 'https://corsoitalianspecialties.com');
  define('HTTPS_CATALOG_SERVER', 'https://sperdie.fatcow.com/corsoitalianspecialties');
  But still no change - Keep getting error.
  Contacted the host company and they said that the problem is with my "Extras" folder but will not elaborate. Any idea what file in the "Extras" folder could cause this?

Ignore the part: "Getting error:"This is a non-secure form.
This form will be sent in a way that is not secure. Are you sure you want to send it?" Then the user and password disappears and asks me to sign in again.
So..." as that was due to the misdirects, that did not allow me to sign into the Admin. I can sign into the admin now after changing the configure file.
So my only issue is with credit card processing.

Assuming that yourself tested the link given to the host and found that there were errors still, then your host still has not resolved the issue. The SSL related issues identified by that test are not related to customers accessing your site, but your site talking to other computers/sites. Further if the host can't seem to understand that difference, then perhaps it is time to find one that does...

I was not sure of what the expectations are when I go to
http://corsoitalianspecialties.com/extras/curltester.php
So going to that url from my computer, I get message:
Forbidden
You don't have permission to access /extras/curltester.php on this server.
That directory "/extras" is where they told me the issue was but could not tell me any more.

OK so I removed .htaccess in the "extras" folder.
That allowed me to run the curl test https://corsoitalianspecialties.com/extras/curltester.php
I see error here: "Error 60: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
IMPORTANT NOTE: Error 60 or 61 means that this server has an SSL certificate configuration problem. YOU NEED TO ASK YOUR HOSTING COMPANY SERVER ADMIN FOR ASSISTANCE with fixing the server's OpenSSL certificate chain. "

Are you using Authorize.Net? You might need the new PEM file. It's here: https://raw.githubusercontent.com/AuthorizeNet/sdk-php/master/lib/ssl/cert.pem

Using Square.
I was waiting for a ticket that i submitted to my Hosting service. I noticed that pay by check was the "default" payment method.
I changed the default to Square. https://corsoitalianspecialties.com/extras/curltester.php still gets errors but now it seems to be accepting credit cards.
So issue seems to be resolved.

This form will be sent in a way that is not secure. Are you sure you want to send it?" Then the user and password disappears and asks me to sign in again.
So...
I changed the server address in configure (added s for HTTPS_SERVER)
define('HTTP_SERVER', 'https://corsoitalianspecialties.com');
define('HTTPS_SERVER', 'https://corsoitalianspecialties.com');
define('ENABLE_SSL', 'true');

define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');You'll need to also add the s above to make https work in the catalog.

I was having the same issue, then I found that my square account needed to confirm I was able to take payments. It's part of the set up process.

There is a Green Button, Top Right of the Square Dashboard saying set up guide. You will see an option in there saying 'Take your first payment'. You must click on this and take your first payment by clicking on that, not through any other method. Send yourself an invoice for £1 or $1 or whatever currency you are using and pay for it on a credit or debit card. That will confirm your account set up and will allow you to take payments through your website.

You need to leave it a few minutes to finish processing the account set up though, so don't try immediately after account set up. Image attched.

I now have the same problem, and using Square Up. Your image does not open for me. Logged into square, I do not find the dashboard link with the Green Button to click either. Under my Store, there is nothing like that either.

I'm thinking that maybe things might have changed in 6 years. :P

Let us know your ZC version, PHP version, and Square WebPay version.

You might try posting this in the square_Webpay support thread, but it kind of looks like the site's not receiving its access token.

i would suggest reviewing the zen-cart square documentation.

the error message is pretty clear.

ensuring the your application is properly provisioned, and that you have a valid OAuth token can some times be a challenge.

but you are communicating with square, and square is telling you what is wrong.

best.
