I apologize for opening this post, but I’ve already resolved the issue.
The problem was with the HostGator server in Brazil.
When accessing the video URL outside of Tutor LMS, it caused freezing on some devices.
I reached out to HostGator support, and they informed me that I couldn’t store videos on my hosting plan. They advised me to use YouTube and set the videos as “unlisted.”
I found this solution excellent because, with Tutor LMS, it became very secure, and the video source cannot be accessed.
Thank you very much for your attention, everything is resolved!
