Early termination of tenancy without penalty due to COVID-19

Hi,

I have a 1-year rental agreement with 4 payments in a year in the form of PDC. I went on a normal 1-month vacation with a return ticket, but unfortunately, all flights were suspended and travel restriction applied due to Coronavirus.

Now for the last 2-3 months, I am in my country and unable to join work but my landlord said I have to pay money from my country.

How can I pay with no salary and I am stuck outside with no guarantee what will happen next?

Out of 4 cheques, 3 easily cashed with no problem but he said pay half cheque amount in May and the remaining in next month.
