Yes, I had imagined this to be easier than it actually is. As so often in life, I was proven wrong by the resistance of the server configuration. The only "excuse" I can give myself is the fact that after 25 years of creating websites, this is the first time I've ever taken this step. Quasi from web designer to server administrator.
But of course I'm not beaten. I will continue to work on the configuration and setup of the server, but in order to keep to my schedule, I will first devote myself to priority tasks, such as solving the upload problem with the video cloud. I still have the beginning of May in mind as the date for the launch of the online community and I will definitely keep this date.
