wordfence h5p malfunction


We installed H5P plugin on 2 websites on 2 different servers, on wordpress. On one site the content is displayed and the plugin is working as it should. On the one we have Wordfence installed, everytime we acces the plugin UI and try to create content we get disconected and sometimes we get the error: Invalid security token. Are there any firewall rules that we should add in wordfence so that the plugin can connect to the server from where it downloads the content?

On the other site, without Wordfence, everything works great.

Thank you!
