Problem Description

Issue

I’m unable to start the server after I updated server version from 1.21.11 to 26.1.2. I’m using latest java version, not sure what am I doing wrong.

Reproduction Steps

  • updated AMP because server was not starting
  • changed version from 1.21.11 to 26.1.2
  • removed all plugins because I thought they were the issue
