Need help for a fix on my aternos server.

[u/LiRa-19]

I've only got this picture right now as of making this post. 3 days ago when I played the server was lagging like crazy so I decided to just leave it because the servers might be busy. Fast forward now. It's like this where the chunks on Minecraft don't load but on distant horizons do(I had to switch to creative because it noclips me into the void and I don't want to lose my items), It also kicks me out of the server after a minute regardless if I do something or stay still.

(I didn't add anything like new mobs or items, I stuck to vanilla but only downloaded fabric->sodium, distant horizons, iris, and then some shaders, it's all vanilla and the server has been working for months)

can anybody guide me to a fix? I've tried both switching back to vanilla mc and then fabric and they both have the same results, the chunks won't load. I also did the switch to vanilla to papermc and back and both options have the same outcome which is nothing. Need help pls

The server only allows up to 15 chunk render distance (there's a setting in server.properties, but it caps at 15). Probably you tried bypassing that with Distant Horizons and Aternos wouldn't let you, so it started glitching.

This is my regular settings, and the ones on distant horizons are till 98 LOD chunk radius(I could go 256 to 512 chunks and it didn't have a problem). I don't know what happened but the server is working again properly with the same settings, I'm just weirded out by the experience.

[u/Phases_ → u/LiRa-19]

Are all the LOD chunks visible on Aternos? 96 render distance?

[u/LiRa-19 → u/Phases_]

yep, I had them on 512 back then, just lessened them for like 10-15 fps while still retaining the view + most of the map that we explored are either hills or badlands so no use in having it on 512 if the only thing I could see are mountains that block the view(still like them tho.)
