When I try to access the forum in my VM, the below error is shown at every webpage I attempt to enter.

Fatal error: Uncaught PDOException: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/Connector.php:47 Stack trace: #0 /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/Connector.php(47): PDO->__construct() #1 /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/MySqlConnector.php(20): Illuminate\Database\Connectors\Connector->createConnection() #2 /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/ConnectionFactory.php(57): Illuminate\Database\Connectors\MySqlConnector->connect() #3 /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/ConnectionFactory.php(46): Illuminate\Database\Connectors\ConnectionFactory->createSingleConnection() #4 /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/DatabaseManager.php(176): Illuminate\Database\Connectors\Connectio in /var/www/codoforum/sys/vendor/illuminate/database/Illuminate/Database/Connectors/Connector.php on line 47

I haven't made any changes to the forum prior to getting this error and I am not sure what may be causing this issue.

Maybe this wil help you: Link to a Stackoverflow Post about that issue.

Kind regards, WebCrew

So it seems like this error is coming from the PDO statement creation from the createConnection function.

How would I be able to trace back the parameters that might be giving the problem? (Sorry I don't have programmatic knowledge in PHP to be able to debug this myself.)

Hi

What parameter did you give for host when you tried installing?

I'm not quite sure as this particular instance wasn't installed by me. I do have access to the VM where the DB is installed in case it is stored within there.

It will be difficult to identify the root cause.
Why not install codoforum via docker? We do have a directly installable docker image.

It's not intended for production use but you can atleast test out the features.

Reinstalling should be no problem. My only concern would be whether the posts made on the non-working environment can be preserved and clone to a new one.

Would this be accomplishable by cloning the DB and the image files that were are linked to the DB to a new forum environment?

If it's also Codoforum then you should be able to import your old post table into the new database - I think that will work.

Kind regards, WebCrew
