Hello. I have an Aternos server, which has a small amount of mods, and never used to lag me. My client averages about 20-25 fps. However, recently my server started lagging hugely. Elytra does not deploy. Any kind of flying from me will return the message 'Exabyte314 moved too quickly!' in the console and teleports me back. Minecarts move a block, stop for 2 seconds, move again, stop again, and repeat this for the entire trip when they used to run smoothly. My server depends hugely upon minecarts and Elytra to function with transport. Sometimes, when blocks are destroyed, they will disappear for a second, reappear for a second, then break.
Extra information about server:
Modded, using forge 1.12.2-14.23.5.2838.
Mods - CustomNPCS (30Jan19), davincis vessels (6.340-full), mrcrayfishs furniture mod (6.3.0), journeymap (5.5.5b7), malisis [blocks (6.1.0), core (6.5.1), doors (7.3.0)], movingworld (6.342-full), worldedit-forge (6.1.10 SNAPSHOT). I have been using these mods for the entire time the server was being used. This only started today. All of these were the recent latest versions and never caused me problems before.
Player count - always 1, always me.
Version - 1.12.2.
I have tried this on multiple Wifi networks, 2 in total, and 1 of them in multiple places. Always this lag. And the one I tested in one place is a very good wifi network.
It might be worth noting that this started as soon as I changed my video settings and improved them, from 10 fps limit to unlimited, which was when it started averaging 20/25.
Thanks in advance!
EDIT:
Now it's not letting me in. I get in, 5 seconds later it says 'An existing connection was forcibly closed by the remote host.' The Aternos console says I timed out, when I am in the process of attempting to destroy a minecart.
EDIT 2: Would the reason for this be that I have 2 separate Minecrafts open with 1 directory, in different versions? I have been doing that for a while and it never did this before.
EDIT 3:
Okay I restarted it and it is letting me in, but still the lag.
EDIT 4:
After this started, I have added IC2 Classic (1.5.4.3.2)
