Problem with Connection to Syncthing

Hi gadget,

thank you for your long text. The adress http://127.0.0.1:10080/, dont work. The browser says: ERR_UNSAFE_PORT

I use Brave.

The problem is that I haven’t reconfigured anything in Windows. I simply haven’t used Syncthing for a while. But I didn’t knowingly change anything. So I can’t say what the problem is.

I have fix it. The problem was, the unsafe port. With --explicitly-allowed-ports=10080 into a chrome shortcut, it runs :D.

Thank you for your time guys!!

Port 443 is the official HTTPS port reserved by IANA, not 433. You can use any port that is not used by another program for any protocol though (that includes 433 for HTTPS, if unused by any program).

Also even if a port is reserved or registered by IANA, does not mean you strictly cannot use it for a different purpose than is defined. But I don’t know if that’s what you meant by “reserved”.

Also, from the IANA Port Number Registry page:
