Website link to change wifi password appears broken

Hello!
I am setting up my new gl-sft1200 and the website link to change the wifi password appears to be broken. Any time I type it in or even click the link provided on the QR code support site, it says "this site can't be reached." Does anyone know how to fix this problem?
Thank you!

Please share some screenshot to detail know.
What link/QR code you mean?
