Server Crash With No Explanation Whatsoever About the Cause

I have made a private modpack to play with my discord friend on Aternos, and it crashed. I know for a fact, that if Aternos servers crash, it provides detail about the cause of the crash, for example, Dynamic Trees - Reinstall/Delete or something like this. But this time, there was no descriptive explanation of the cause, and yes I did look at the logs, but I see no potential cause for the crash. The warnings were mostly about prefixes, but I don't think that's crash worthy, and the log continued on from the warnings so I doubt it's that. Also, the log didn't even highlight the part the crash happened in, and I see nothing about the crash report being saved, therefore no crash reports (I checked) Also, I did test this modpack by myself on singleplayer and it worked flawlessly. I seriously have no idea what is wrong. I see absolutely no potential causes for crashes in the log, and I don't think it was even registered as one. So, please help me. I have spent so many hours of my life into this modpack, and I don't want it go to waste. The version is forge 1.12.2

I see. But is there really no solution other than this? Modpacks like sevtech ages take way longer than this mpdpack to load yet works in aternos. Is there truly no solution other than this? Since there is a dedicated map for this modpack, I do not want to remove mods if possible in order to not break anything.

Anyone? I seriously need help with this

Quote from Roman

That pack is not available at Aternos...

That's not the point. I was just giving you an example of a working modpack. The point is, is there any other solution than this? Because I don't want the map to break. Also I don't even know what mods I need to delete. (Maybe Lycanite's Creatures? But that'll break everything.)
