Merge SSL cert request

Hello,

I am getting this error “Certificate signature does not match contents” when…

SSL request is expiring on server so, I created new request(option1) and send to CA(option2), than I imported Root CA into kyr file (option3) and when CA send me back signed request I tried to import them into kyr(option4). Anyway when I try to merge signed request I am still getting erorr

““Certificate signature does not match contents””

(other server few months ago, I merged ssl request without problems)
