Posting to Panel source

We have written a post to a panel and it's been working for over a month and now all of a sudden it's not working. The only change that's been made has been an update to the url going from njcaa.imiscloud.com to connect.njcaa.com. We are logged in as a company administrator of the organization we are posting. We are still able to post to activity without any issues but panels are not. Example post:

jQuery.ajax({
"method": "post",
"url": String("https://connect.njcaa.org/api/NJCAA_ASC_P_LOIHistory"),
"headers": {
"RequestVerificationToken": jQuery("#__RequestVerificationToken").val()
},
"dataType": "json",
"contentType": "application/json",
"data": JSON.stringify({
