Welcome @Meni, local network LAN not local machine!

Did you test it on the network? or dotnet core 7 ?

Did you test it on the network? or dotnet core 7 ?

Did you?

Perhaps you could tell us what you have tried and what results you got and someone may be in a better position to offfer some assistance.

Did you?

Don't take it wrong.. I see the question is clear and it is a usual process for developer.

Until I find a solution you're welcome Huw Reddick.

I tested that before but not working..

What doesn't work? Did you open the ports on your firewall?

I don't know much about the MAC, but your problem is you are trying to bind a https address without an ssl certificate.
