Issues uploading H5P book

I recently created an H5P interactive book in Moodle, I downloaded the file from there and tried to upload it to my account but it won´t finalize the process. I´m able to upload the file and it shows the message that says 

Interactive Book was successfully uploaded!

But then when I hit the Save button it will keep Loading forever... 

I already tried to do this in Chrome and IE, without any luck, my h5p file is 2,305 KB, so not that big either. My internet connection is strong also. 

Thanks for the advice!

Hi kpereira,

I can assure you that uploading into works fine. I just tested the sample content and I was able to upload it here: There are several factors that may cause this, and it will help to isolate this if you upload your content here.
