HI,
Thank you for your answer. I looked at the problem indicated for Talk HPB but I don’t think it can help me at the moment.
I will use the Talk application to hold meetings with over 5 people and therefore I read that I should install and configure HPB but it is not clear to me how to do the installation, whether I should use a different server or install everything on the same server where Nextcloud resides. Please could you help me? Sorry, I’m new to the Talk app.
