Why does my dedicated server crashes when loading a map that uses the water plugin?

Thanks, when packaged it runs correctly, but the server is not found by the client.
The client gives me a log line with something like:
Server [My public IP] failed to respond
Before i had the water issue i had this issue, which i fixed, clients could connect to the server. And i started having the water issue when i made the server’s map contain water. No clue how i fixed it though. Maybe the reason it stopped working is linked to the fact that my .ini files keep changing by themselves?
