Increasing the mobs spawn rate

I already read some of the thread about this, is there possible for Aternos to make a settings to increase/decrease the mob spawn rate?

Its kinda weird, like literally i think is not just me, but everyone's server there is just a little bit mobs spawned around..3-5 mobs around then after the mobs were killed, there are no more mobs after that..even it is in Hard difficulty..

Its kinda boring for my server...tthere are no challenges, better equip but lack of challenges..

Edit: i am using 1.14.3 versions of Minecraft

1.14 and newer versions are known to have serious problems regarding mob spawning which is probably the cause for your issue.

Right now 1.14.2 is known to be quiet stable regarding mob spawning. Please try to use that version.

You can switch your version on the software page: https://aternos.org/software

What about the render distance of the server?? Can you explain why you guys limit it, its kinda passive and not satisfying with my higher render distance of my minecraft but still cannot see the mobs spawn from far away.. 😂
