already installed or misconfiguration

[bnkcrypt]

I installed a new machines with nginx , php7.2 has fresh mysql with empty new database name "pdns" when i open the setup link it show me setup form and after filling it I get the follwing error

The application has already been setup or the backend is misconfigured.

Its a fresh machine nothing configured before, php works fine so does mysql . mysql is localhost and has the required clean new empty db .

How do i resolve the issue ?

By the work just to trouble shoot I tried to enter wrong db password to the setup work it show me exact same error seems like its not even trying to connect to db . Are there any libraries for php required if that could be the case .

I have exactly the same issue.
The only difference is, I'm using Apache.

[vhostvn]

same issue here

In the current master branch I clarified the error message. This comes most likely from a misconfiguration of the backend server. It is issued if the call to the api returns with a 404 error. Please provide the configuration you used for your apache vhost.

I have the same Problem.
This looks like the second Rewrite to the index.php did not occur.

I am getting this error on centOS8 fresh installation, Document is very poor so hard to resolve it. any suggestion?

[loewexy]

I can not support other setups, but the problem should always be that the backend is not configured correctly. Since it uses the Slim PHP Framework, maybe you can find hints on using Slim with apache and centOS8.
