Error BLZBNTBGS0000004A - App Download

Does anyone know how to fix this error? Blizzard support is ridiculous, I can’t download the Battle Net application from Setup, the download stops at 25% and a window appears with this error, none of the solutions recommended by the site solve the problem, it’s a matter of line as it gives me the usual error also on the laptop, I tried to open the firewalls and connect the line from my phone to the PC with hotspot but the error persists
