When i put my terraria server to version 1.4.5 and when it's done creating it's now version 1.4.5.5 and i can't play it, is there a way to fix this?

What is your terraria game version?

it's version 1.4.5.0

To change terraria server version(example to v1.4.5.2) in control panel:
1. Make a backup
2. Select correct version in server settings
3. Reinstall server
4. Enjoy
