There are several reasons why your server might not be starting properly. Here's some things to check before sending a support ticket:
- Ensure your server version matches your world version
- Check your plugin folders and Skript backups to see if you have a large number of files, you could be at the max server size
- See if your whitelist is enabled, if so ensure that you are added
- Double check plugin settings to ensure they are not broken
- Check if you have an excessive number of items or mobs spawning in a location
If you're still having trouble or are unsure how to check any of the above please send us a support ticket and we can help!
