Seems my developer and Kosmos/Web Integrator (Handles stock/images/product information and our inventory system RMS) are stumped on this one. We just updated our website to https and now we are getting an error when Web Integrator tries to connect to Magento "Unable to Connect to Website. Please Checkout Your URLs and Try Again".
The easy fix would be oh, we just need to change it to https, which we did, but my developer is saying that he doesn't even see an attempted connection.
Does anyone have any ideas to this? I can provide more information if needed.
Since that is a custom software, I would suggest that they should look at the code that they implemented to connect to Magento.
It's almost impossible to determine the reason for the error since we don't have access to that custom code.
Good luck with that!
Is your certificate valid? Is it valid to your integrator?
Can you connect with a known good or very simple application?
FWIW I'm using Let's Encrypt with Magento 1.9x and it is having no issues with SOAP integrations so far.
So this is what my developer found. The software is pretty old and is not being upgraded anymore. It will not work with https. So he has reverted the site back to http for now (we had to do a few functions). He is working on figuring a way to allow the http-https redirect on all pages except the one that this software is calling.
Anyone ever done that?
