For help regarding Aternos, we recommend you to visit our support center.
I know your recourses are limited but try to make the servers 24/7.
A tip for that not have it online all the time have the plugins and mods online then when ppl join it starts after like 30 sec.
And ik afternos is supposed to be free but I would gladly spend 30 bucks for an easier domain with less server lag.
Then you could focus on more memory for the aternos community 
Running your server 24/7 is not possible because we are a 100% free service. We only have limited resources, and we want to make sure that these resources are used by active players.
Trying to circumvent that is a violation of our terms (https://aternos.org/terms) and will result in your server being suspended.
Aternos is a 100% free host.
If you want a paid server check out https://exaroton.com/.
exaroton is a paid host developed that's very similar to Aternos but offers better performance and additional features that just aren't possible on a free service.
