Things are progressing: now Error 404 appears starting the client.
Thanks to the admins! We realize that this a double edged sword (bad pun), but it also wasn't your fault at all. Next time it's going to happen, I will look into my crystal ball and call you 😁
If anyone is to blame for this, then it is OVH. They should have Fire protection and prevention in every single room and simply didn't. End of story... How the heck did a burnt out UUPS cause this ???
