Good evening, I'm completely confused. It turns out I installed a new ubuntu server and installed everything that osticket required. If I create a new database, then through setup I create a new file ost-config.php and everything works fine. But I need a database from the old server, I import it to the new server in mysql, in the ost-config.php file I write the name of the database where I imported the old database in advance. I will provide in ost-config.php the login and password that root has in mysql. But still the database does not connect. It says the system is not available. I'm trying to enter logins and passwords from the old server but it doesn't work. I also tried to create a new administrator user through mysql, but I also can’t log into scp through the browser.
I'm at a dead end and can't understand what exactly I'm doing wrong, don't judge strictly, I just recently started learning Linux.
