You're probably using the wrong password. You can use this page to set up a new password
https://www.heliohost.org/password/
Please be aware that the page will only securely submit the password to us, so the new password won't work until I manually assign it to your account. Your plaintext password will never be visible to me or anyone else. Once you have submitted the new password let us know and we can update your account. Since cPanel doesn't work anymore you can't change your password yourself directly so I created this page as a work around.
No problem. Thanks for the donation, but we have to draw the line somewhere. We've existed since 2005 and someone who donated 16 years ago probably isn't around anymore so most of the old donations would be a waste of time to calculate.
We lost our licenses on 2021-07-14 so all donations after 2020-07-14 count towards the Plesk transfer order. Your donation was in 2019 so it is outside the range.
If you upload your new private.key, ca_bundle.crt, and certificate.crt to your home directory I can install the new ssl certificate for you. Most people just use the free zerossl certificates, or let's encrypt.
