Wrong dbport used instead of the configuration one

The issue you are facing: Nextcould try to connect on postgres servr port 5432 while 5434 is configured
Is this the first time you’ve seen this error? Y

The output of your Nextcloud log in Admin > Logging:

An unhandled exception has been thrown:
Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[08006] [7] could not connect to server: Connection refused

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

grep db ./config/config.php
‘dbtype’ => ‘pgsql’,
‘dbname’ => ‘petitnuage’,
‘dbhost’ => ‘localhost’,
‘dbport’ => ‘5434’,
‘dbtableprefix’ => ‘oc_’,

Yesterday, everything was working perfectly. I did not…, I think I did not…, do anything special since my last connection.

So, how does nextcloud look for a 5432 port while it is configured for 5434 one since the beginning a year ago !

Thanks for your help.

Have you tried to set the port within the dbhost parameter and remove the dbport parameter?

'dbhost' => 'localhost:5434',

Check where the MariaDB is running:
netstat -tulpen

Also you can use another configuration look this post.
Do you use/need IPv6? If not deactivate it.

Yes, it was has this before the problem occured, and I had changed to see (and I saw :slight_smile: )

I use postgresql

Sorry. My fault.

Have you read this documentation. You can use the port with the path to the socket-file. Perhaps this configuration help you.

No Problem.
Yes, but it does not help. I have no logs to tell me where it goes to take this wrong port parameter. It is amazing ! I had tried to connect to the database it works perfectly. I had check permissions on different files, socket included. I am stuck here with absolutely no idea of what could happen.

So I had modified twice the config/config.php as follow …

  1. modified ‘dbhost’ => ‘localhost’ to ‘dbhost’ => ‘localhost:5434’ kipping ‘dbport’ => ‘5434’

Tried to set maintenancemode to off and I got a different kind of error. Then, I did
2. modified ‘dbport’ => ‘5434’ to ‘dbport’ => ‘’ and kipping ‘dbhost’ => ‘localhost:5434’

Tried to set maintenancemode to off it replied that it is already off, meaning that it works. Indeed, it works !!!

The error log…
