Confluence can't connect with postgresql database
Asked by mkrupniewski-blueowl:

I install Confluence according to the instructions using Nginx and proxy, I have an empty postgresql database. During installation, when selecting a database, I enter the database data, click test and everything is ok. However, when I click Next button, so that the application connects to this database, for about 2-3 minutes the page tries to reload and then pops up 504 Timeout Gateway error. At the same time CPU consumption reaches 100%, then I have to reset the VPS server.  
I have no idea where the error is: have I configured something wrong somewhere? Is there something wrong with the database? or maybe the server does not withstand (1CPU, 2gb RAM)?

body: Mayby 1CPU and 2GB RAM not enough? I found this -\> <https://confluence.atlassian.com/doc/server-hardware-requirements-guide-30736403.html> and server should have at least 6gb ram,...?

Please check for any errors in the Confluence log file. Which is found under:

```
<confluence-home>/logs/atlassian-confluence.log
```

comments: author: mkrupniewski-blueowl
body: there is no such file in this folder


author: Edwin Kyalangalilwa
body: Ok, check under:

```
<confluence-install>/logs/
```

This will give us a definitive error. If it's memory or something else.
