When I start gateway, it is written “gateway not running” on the title of page. I checked my java version.
Modern Ignition uses its own java, not your system java. Look in your gateway’s install folder’s log folder and look at the contents of the wrapper.log file. It should have clues why your gateway isn’t starting.
Thank for your reply. All logs in file is like this.

There’s no useful information in that snippet. You probably should ask support to look at your machine remotely. (This forum is not official support.)
