so when I try to download this modpack called PokemonUltra, I get this error message: I have tried a lot to fix it like removing the modpack and trying to install it again, Deleting and redownloading technic launcher, I added both the minecraft launcher and technic launcher to my firewall allowed apps, I have the latest version of java, and the modpack, but none of that is helping, I have tried contacting the modpack owners but I'm not getting an answer. Does anybody know how to fix this?
