Municipal Corporation Of Navi Mumbai — property tax payment online not working

Address:

Municipal Corporation of Navi Mumbai

I have been trying to use this link for payment of property tax (https://www.nmmc.gov.in/property-tax2). since apr 1, 2020 till this day 15-jun-2020. Link is not working.

There is no other option to pay online viz. Paytm, etc. Why are they not concerned to rectify to collect the taxes? Are they so lethargic to rectify the revenue generation connectivity?

Please forward this concern and arrange to rectify the same at the earliest.
