Please help?! Trying to resolve Paypal IPN ISSUE

Trying to resolve this Paypal IPN and web return issue so I ran the response test from this link

What's happening is that payments made via Paypal are coming through, but not hitting back to the store. When I run a test purchase, after making payment via paypal I am returned to a BLANK PAGE (no visible error message) on my site. The web return url is set for shared SSL:

https://mysite.com/~clientname/shop/index.php?main_page=checkout_proces

IPN CHECK returned:

IPNCHECK.PHP - Version 1.0

IPN TESTING - POSTING to PayPal via: ssl://www.paypal.com:443

IPN TESTING - Confirmation/Validation response: RESPONSE RECEIVED - Communications OKAY


Script finished.

Curl test returns:

7 couldn't connect to host

My hosting company enabled open_url on my php.ini which is still not resolving the problem. (and now they want to charge me for support at $60/hour -- which I would, frankly, rather pay to someone who KNOWS zen cart instead of these guys who don't)

Any clues?

THANKS!

Hi,
Apparently paypal had serious IPN problems a couple of months back and I'm wondering is the problems are back.
We got an order but it did not make it through to the zencart system.

Same situation here, and I'm trying to resolve that. I have the following in the email log (with debugging on):

IPN INFO - POST VARS to be sent back for validation:
To: www.paypal.com:80
POST /cgi-bin/webscr HTTP/1.1
Host: https://www.paypal.com

IPN FATAL ERROR :: Could not establish fsockopen.
Host Details = www.paypal.com:80 (110) Connection timed out

Trying again without SSL ...

IPN FATAL ERROR :: Could not establish fsockopen.
Host Details = http://www.paypal.com:80 (0) Success

Trying again without specified protocol ...

IPN FATAL ERROR :: Could not establish fsockopen.
Host Details = www.paypal.com:80 (110) Connection timed out

So now there are two.
Can someone confirm that paypal is having a problem? or confirm that paypal is not having a problem? If the latter, what should we look into?

Ok, mine is working now. My host unblocked port 80 (I have no idea why it was blocked -- or if it should be). But I just ran a paypal test and it went through properly this time.

My host says port 80 is absolutely not blocked.
can someone please help unravel this problem?
thanks

Did you resolve this?
I'm still getting the paypal invoices/orders showing up in the admin listing BUT no emails are generated. This makes for a lot of extra work.

I always get email when credit card payment is approved/authorized from authorize.net, so I know my email settings are correct. What's the deal with Paypal emails?

I really never expected the paypal module would be my biggest problem :( so strange!!
