What is your JSS running on? Linux, Windows, macOS? Is your database on a separate server? Was this working before you were trained? Sounds like you should grant user privileges to the database first using the GRANT ALL command in MySQL.

macOS, it's on a separate server. It was working before and continued to work until about last week. The server was upgraded and I'm sure that had a part in it.

Nevermind, problem resolved. Thank you so much.

I forgot to turn MySQL back on.

We had that issue earlier this week. I chalked it up to a failed upgrade to casper 9.97.

Jamf support and I eventually used the flush-hosts command in mysql and everything started talking immediately. Some documentation from mysql on the command is below. Basically I am assuming my app server flooded the mysql server with bad requests and the mysql instance ,detecting a DDOS, turned off access for the app server to protect itself.

I am running into the same issue as well. Just recently updated to the newest version, and got the same error message above. I am running a Windows server and I have verified that both the Tomcat and MySQL services are running on the server. I did attempt to get into the MySQL command prompt, but unfortunately I do not know the root password. :(

Any thoughts on how I can fix this issue? I want to try to fix it before school resumes tomorrow.

Thanks!

UPDATE: I apologize, the error message is different from this post, so please ignore my message. I will post a new message. Thanks!
