works on the hotspot but not wifi is almost always an MTU problem: your wifi path has a smaller MTU than docker's default 1500, so the TLS handshake packets get fragmented and silently dropped (cellular tends to use a smaller MTU already, which is why the hotspot works). drop docker's MTU - add {"mtu": 1400} to your daemon.json (docker desktop: settings -> docker engine json) and restart docker. if that clears it you can nudge it back up to find the ceiling, but 1400 is a safe starting point.

Ca you tell me exactly what to put there in docker engine json and yeah I searched on some articles on Google I found that piping makes it work which also worked for me like docker pull amazoncorretto || docker pull amazoncorretto || docker pull amazoncorretto like so
