First, note that the Billing Portal and the Support Portal are logged into with two separate accounts. Although there is a link to the Support Portal from within the Billing Portal, that does not automatically log you in.
To log in to the Billing Portal, follow these steps:
For your convenience, there is a link to the Support Portal, visible from the Billing Portal Dashboard.
However, you will not be automatically logged into the Support Portal by clicking on this link. You will still need to enter the login information for the account for the Support Portal. This might have a separate username from the one used to log into the Billing Portal.
You can also access the Support Portal by typing directly into your browser's url bar https://support.knownhost.com/.
Once you have accessed the login page for the Support Portal, you will need to log in before you can submit a Support Ticket.
If you do not first log in, you will only have access to create tickets with the Sales Department. If after clocking the "Submit a ticket" button, the page looks like this, you have not yet logged in and still need to do so.
Using the login box for the Support Portal is similar to using one for the billing portal, except at a different url and possibly with different login information.
