Unable to relocate database

Hello everyone,

Recently, I had to relocate the Invoiceplane database to another IP. I changed the hostname in application/config/database.php:
But it still throws a database error:

Unable to connect to your database server using the provided settings.
Filename: third_party/MX/Loader.php
Line Number: 99

Invoiceplane and the database are on separate servers, but I can connect to the database from the Invoiceplane server.
How can I solve this? Changing the hostname doesn’t seem to work.

Sounds like the MySQL server is not allowing connections from other hosts either for the whole server or the single user. Please check both configurations.

Yep, that solved it. I missed a setting on the database server which prevented connecting from the new Invoiceplane IP. Thanks!
