OK Guys, I am pulling my hair out. My initial issue was that the instructions said to go to the following address in the browser:
"You should be able to browse your wiki at http://localhost:9090."
When it should be: http://SERVER-IP:9090/mw-config/index.php to reach the installer.
Now I can access the installation site for MediaWiki, I am still unable to connect it to a MySQL database. I will include screenshots to help assist in finding a resolution to this issue. (Side note: I currently have Nextcloud and MariaDB installed but is currently disabled. I have tried to use a different port number for mysql other then 3306 but have decided to temporarily to disable MariaDB and use the original port. Clean installations of MySQL have been obtained when settings were changed to further diagnose if it is a SQL error or an issue with MediaWiki docker)
I have tried localhost, 127.0.0.1 as well as the IP of my unraid server without any luck of connecting. I have tried simple to complexed passwords and I still receive the same error as shown in the screen shot below named "ERROR". I have tried everything to make this work that I am aware to try. I do not want to use MariaDB for both Nextcloud and MediaWiki. If you can assist, please let me know.
