Cowin portal is waste bro,it is not showing all the centers,and available vaccine slots.
In Telangana every dedicated vaccination centers are giving free vaccine but not showing in COWIN,I don't know why.
In private centers or government centers if u visit personally u will know the situation.
Iam also waited a lot for vaccine, but when I contacted hospital directly they said vaccines r available.
Situation is same in AP also, I think state governments created seperate app for vaccines.
Hope it helps who r waiting for their shot.
