Editing error in any Moodle H5P activity

Hi All,

First of all, thank you so much because I always benefit from the information I read here. From now on, I'll try to contribute more. I am experiencing a problem that suddenly start to happen. When I try to edit any kind of H5P in a Moodle 3.5.7 I have the same error message. I've turned debugging on and had different messages in my stage and production envionment. Any of you had this problem before? We have many different security configurations on server and different firewalls, do you think that those firewall could be the problem source? 

It was working before we updated moodle from 3.5.1 to 3.5.7. I can see contents and activities, I just cannot edit them. Thank you so much.

In my stage I have this message

error/invalidhvp
