You had to type in /fml confirm into the server console when asked for it, not just anytime. I've done that for you so you don't have to do it in future anymore unless the mod pack gets updated.

The error message says that there was a problem with minecraft.net, and minecraft.net is not affiliated with aternos.org in any way. Meanwhile the problem should be fixed already, so just try to join your server again.

Thank you for reporting this, we will investigate this further.

Dein Server scheint offensichtlich zu laggen. Stelle sicher, dass die Welt nicht zu groß ist, und keine riesigen Mob-Farmen oder Redstone-Maschinen Lags verursachen.

Create a server-side version of the mod pack.

Just go to the files & plugins page and install it, where's the problem?

Download and save your world to your computer and reinstall your server to make it work again.
