can’t upload large file using contact form 7

I am unable to upload large file size. I have posted a question here as well https://wordpress.stackexchange.com/questions/245557/file-size-validation-not-working-for-contact-form-7.

[file* your-file filetypes:mp4|mov limit:40mb]

Following php configuration is set:

post_max_size = 40M
upload_max_filesize = 40M

When I upload video of size 37MB, the loading image keeps spinning no error is seen and when file larger (68mb) it doesn’t show the error message either.

How can this be fixed? I need to implement this on production server without any error. Could anyone suggest how can I achieve this.

Thanks for the support
