Installation and server related problems

Hello, 

issue as described above. It works fine with other content types.

I get the following error notice

Failed to download the requested H5P.

cURL error 28: Operation timed out after 29984 milliseconds with 3587640 out of 4405291 bytes receivedGet help

Not sure what happened, I have updated the library but Step 2 to add interactions is not working anymore,

basically, h5p-editor-iframe is continuously growing the height attribute and showing only black content.

Since I already have created some interactive videos in my drupal platform, is there any way how I could reset h5p without losing them, to rebuild the library?

I have a feeling something is corrupted either in the database or the library.

FYI - I'm running h5p 7.x-1.34 in Opigno LMS (Ubuntu), my library:

When I am trying to insert images in Course Presentation, I get the error message: Invalid security token

I am using Chrome and have tried JPG and PNG.

Thanks
