Error creating new order :too many certificates

Hello,
I am not able to access sites where certificates were installed. I got email, that auto renweal failed. So when I checked both sites on Ceritfy SSL app, it was showing failed. When I tried to renew, then it failed saying Error creating new ordder: too many certificates. So I re-fetched last certificate and then it was showing renewal succesful but site were still not accessible. So I tried deleting certificate for deepaksapkale.com
Now when I tried to get new certificate I get same error "Error creating new order: too many certificates"
so at momeny, deepaksapkale.com certificate is not able to renew and other site even though certificate was re-fetched, site is still down and throw error "ERR_SSL_PROTOCOL_ERROR".
My domain is:
deepaksapkale.com ( tried deleting it, now cannot renew)
researchtech.net (renews succesfully manuall but site still not accesible)

please help
