Huntsman Elite not showing in Synapse and Serial code is incorrect

It used to show in synapse and everything was working well but after a week things started to get a bit odd, the lights are on and they keep on switching colors but i cant find the keyboard in Synapse. I searched it up on YouTube and Google. I did everything i found but it didnt work. So i said maybe i should contact razer and they would help but it tells me to put the category and serial number. ( https://mysupport.razer.com/app/warranty-support/ ) I put "Keyboards and Keypads" and enter the S/N. Its wrong, i keep on trying but it stays wrong. i search it up again and find something but it doesn't work. So here i am after a couple of devastating days hoping someone could help me. Maybe i did something wrong but if anyone knows, please help.
