Hi @fr 

Welcome to the community! In this case, it would be perfect to have you submit a Statuspage support ticket at support.atlassian.com 

Please include the CSV you are attempting to import so we can take a look into that. More often than not the import issues are related to the specific CSV being used. 

We look forward to hearing from you!

Thanks Chris, 

I logged a ticket (SPSP-26875) as suggested and included the .csv file.

Thanks for getting that submitted! So that the suggested resolution is documented here for future on-lookers.

 "I can see the 404 error that you initially sent over. It looks like your network is blocking the upload to the filepicker API. I suggest that you contact your IT team and see if they can help you unblock it from your network."

Please do let us know if this is a confirmed resolution.
