Resolved OCSP ERROR on SSL

[Umbus]

Hello,

I bought an SSL certificate, but when I test certificate the following error appears:
OCSP ERROR: Request failed with OCSP status: 6 [http://ocsp.comodoca.com]

How can I fix this error?
I was searching on google and I think that has to do with the server but do not know how to do this setup ...

It was all the work of nowhere. I apologize
