I was able to use the CSV you sent Joe to ingest these entries onto my own partner.
I checked the logs from your original attempt and I see that, at the time, when our servers tried to download the source entries for the URLs specified in the CSV, access was denied [I am intentionally avoiding actual URLs in this post as it’s public and you obviously want to keep the info private] .
I suggest you try again, since now these URLs are accessible and return the files. Should you have additional issues, please send me a private message through the forum or else email Joe.
Please also note that under KMC->Content->Bulk Upload Log, you will be able to obtain the log for the bulk upload operation by selecting “Download Log File”, this often provides valuable info as to the cause of failure.
