My Aternos Server crashes

Hello!, before you try to help I've already sent a request to Aternos but for now I'm also doing this thread incase if they take too long, aside from that, I recently made a server for my custom mod pack from RL Craft by Shivaxi (https://www.curseforge.com/min…cks/rlcraft/files/2780296) and other mods that I included on curse forge. However after I change and remove specific mods and then I started the server, I get many warnings and later it crashes, I can barely understand Java but the issues seems to be with Minecraft's Java and not a mod specifically. This is the log: https://mclo.gs/2zjLm1E

Okay thank you!

nvm it didn't work log: https://mclo.gs/RHOX9sr

Its okay, I just deleted ice and fire dragon, sense i tried downgrading and it didn't work, but thanks for the help!
