So i host a server called ChingaSample.aternos.me and is in Forge 1.12.2 (14.23.5.2847) and i have 4 mods installed on it: General Disasters 1.0, Mutant Beasts-1.12.2-0.7.1, Respawnable-pets-1.0.6.1 and Standabilitymod v1.8 (1.12.2)...
The problem is that, while one of my friends with the same mods can enter, me, who is the host (and possess the mods too) cant get in because of the error... the more frustrating part is that that same friend whose server is tucaralandfsax.aternos.me with the same mods and same forge from aternos, could create the server without any problem, and even me could enter
But i still dont know why mine doesnt work, i had other mods installed and the only one who desinstalation apparently fixed the problem was a prehistoric one
The log only indicates me, mostly, problems with FML Core but i need help with that... so please if you guys could help me 
Here is the Log
