"Finished search with no results" The server is multi-version compatible

[JoeIsOnABoat]

Hello to whoever is reading this.
im having a problem trying to find the seed of a server, the version is multi-compatible ranging from i think 1.20 or 1.20.2 and under. so i dont know which version to use.
the server is run using MCProhosting if that helps.
i have tried finding more structures, didnt work, tried switching the version to 1.16.4 and 1.18.4 i think, didnt work.
i have installed the 1.19.4 version and used it, didnt work.
please do help as i have tried reading other forums, but none really seemed to work.
The thing that i think might be causing this is that it is multi-version compatible.
please do look into this help, thank you.
