Cannot login with my admin user

Hello team,

I have on-prem MSP SD plus installed and implemented for more than one year.
But there was no access to it for a long time and need now to re-activate.
when I enter the password it doesn't give any respond , it just refreshes and clear the fields.
Tried to click forget password and entered all my emails but didn't receive it.
May be the licesne should be renewed, but I cannot login even to renew the license.
Please asssist.
Thanks
