Connection Refused when trying to access API

[ltp_devin]

Hi All,

For the last two years we have had a cron script that grabs inventory information from our Shopify store for use on our site through a private app.  We use the following endpoints with this script:

/admin/api/2021-01/products/count.json
/admin/api/2021-01/products.json?limit=250&published_status=published

This script has run without problems until about three weeks ago when we began to get this error:

Failed to connect to norco-com.myshopify.com port 443: Connection refused (cURL error #7)

This error only occurs on our live site, and we can run our script on our local testing environment with no issues.   After speaking with support we believe the problem may have been that we turned on our update script for our new site that was under development at the same time as the old one, which resulted in a large amount of 429 responses being returned.  This has yet to be officially confirmed but that is our hunch.

We have since turned off the extra import script, made sure that our calls were not resulting in any errors and the block still remains (it seems).  Is there anything we can do on our end to resolve the block? We seem to be out of options for troubleshooting on our end and support can't seem to see any blocks on their end.

Any help would be greatly appreciated!

Thanks,

Devin
