Why won't WordPress install on Laragon?

Question

PHP

Why does an error appear when installing WordPress on Laragon – “Error establishing a database connection”? Tell me, please, what is the problem?

Answer 1

Check if the data you are using to connect to the database is correct (try to manually connect to the database using the mysql client).
If the credits are correct, then check if there is a table in the database - maybe it is empty...
