Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Did you copy the contents of password.txt located in your CertSage directory then paste them in the password box before pressing the button?
Note that you can replace the contents of password.txt with whatever you want to use instead of using the randomly-generated password initially provided by CertSage.
Yes, to both questions. Yes, I copied the contents from the password.txt file and paste into the password box and yes, I created my own password. I even had Certsage generate a new password.
No matter what I do, I get "password was incorrect".
I'm at a bit of a loss here. The code that generates that error is so simple that there's practically only one way that error can happen, which is that the wrong password is submitted. Are you positive that you're entering the correct password in the correct password box (there are 3 password boxes on the page)? One trick I can recommend is to temporarily save password.txt with no contents then enter no password when using CertSage. If that works when you previously got an error, it indicates that either you were using the wrong password box or there's some kind of breakdown in communication with your webserver (i.e. something in your website configuration is interfering with posting your password to your webserver).
Interesting. Previously I was just typing "cat password.txt" and coping the password. This time I actually vi'd the file and copied. This time it worked. Not sure why doing the cat on the file caused issues. It shouldn't, but it did.
