I'm getting the CDbConnection failed to open the DB connection error.

The thing is, my database connection seems to be okay, as evident from the fact that the YIIMP logs display the retrieved values that I print out (see the text in the yiimp-logs/debug.log).

I haven't modified the YIIMP source codes besides adding the debuglog lines.

I'm running the server on nginx.

I've tried to figure out where the problem lies but so far I haven't been able to.

What could be causing this issue?

Thanks a ton in advance! :)

ups :( is a common error if you are using by example php8

if you look at your Dashboard you will see the main is in red color that means normally a PHP problem with MySQL or a problem with Mysql

php -v to see your version

You need to be sure you have php7.2 or php7.3 and teh PDO extension

Make sure you setup this:

 apt-get install software-properties-common
    sudo add-apt-repository -y ppa:ondrej/php
    sudo apt-get update

Them use php7.3 or 7.2

update-alternatives --set php /usr/bin/php7.3

again check your server and see is 7.3

php -v

Check your nginx domain config and make sure php-fpm is version 7.3 or 7.2

them if you reboot . Walla all works

Try to use an install scrypt with the last sources version of https://github.com/Kudaraidee/yiimp.git

Updates scripts with Kuraide sources are available in Github up Coleganet but actually are using Docker Container and more advance setup
