Can't add my Leviton Dimmers to Home kit

I haven't been able to re-add my Leviton Dimmers 2nd Gen to Home Kit. I had to delete all my dimmers throughout the house due to a password change with my wifi provider. I have followed recommendations from Leviton, my IT guys, people in the community and nothing. I have deleted them from Leviton and HomeKit apps, I rebooted my wifi, i reset every single dimmer pressing the button and waiting for the green light to blink, I checked and confirm the are using the 2.4 Ghz band, I have followed the steps to add them scanning the QR codes...and nothing. I don't know if I am missing a specific step but when i add the devices to the Leviton app, the process is smooth and they work as expected. The only issue is that I cannot add them to the Homekit app. Any ideas or recommendations are greatly appreciated !!!!
