Wordpress Video Upload Stuck

Hi,

I am facing issue on our Wordpress website https://riotimesonline.com/ that videos are not being uploaded in the media library after CF integration. Initially there was a limit set of 100MB. I have increased the limit from the server end. I am aware that with pro plan (our current plan) the upload is limited to 100MB. But even smaller videos likes 10-15 MB are not uploaded. I have tried on development mode and even paused CF but the videos don’t upload. It gets stuck showing loading status. Any help will be appreciated.
P.S: I uploaded videos on server via host entry, so its nothing related to server.
