Hello,

Yes you can apply for new EWS certificate or renew it online and it will be made within 2-3 days and then you can download it . Have you checked whether there is time left . Try to contact the authorities then they might provide you some time. Do not upload your old EWS certificate as it has expired and it is no longer valid . So, if you submit this then your category would not be considered rather it would be changed to open category.

Hope it helps.

Good luck.
