This past month I have worked to create an 6 point function API to connect with a WMS solution. After I finished editing the iis and other pieces to get our reverse proxy to work, I logged into Epicor. After I click ok, I can get into the classic Epicor. However, when running reports, it fails. I have rebuilt the server and nothing fixes it. I reversed all changes I did for the reverse proxy, still didn’t fix anything. Opening things like Part Tracker give the error of Unbale to login to page. The connection was reset and I can’t move any further.
And after 5 days of digging, and right after I posted, I saw someone else with the same issue. While my fix was different, it led me in the right direction. Basically, I had the server name in 443 binding. I took it out and it worked.
