Hello Vlad,

Thank you for following up.

From our Supported Platforms documentation, Java must be 1.8, or if you’re using OpenJDK, it must be AdoptOpenJDK (Java 8). Some AdoptOpenJDK versions have bugs that impact Confluence. We recommend version jdk8u192 or later.

For the PostgreSQL database, it must be 9.4, 9.5, or 9.6. Anything outside of that is not supported.

I would recommend making sure first that your environment is supported, and then we can proceed from there on getting your installation running.

Regards,

Shannon

Hello Vlad,

Welcome to Atlassian Community! It's nice to have you.

Can you tell me, are you using the bundled Java DK or a standalone Java? What database are you using?

Could you also let us know what version of Confluence you were installing, and the exact method you're using?

Thank you!

Regards,

Shannon
