My Validation code sent to me, wil not work,

I was sent a validation code to input on the link in my email , but when I copied and pasted the validation code it didn’t work, it said “ivalid code”

so i copied and pasted again and pasted in as “plain text” but that didn’t work

the third time, I inputted the code manually and that didn’t work either!!

Now what do I do?? I cannot get my SSL certificate
