Chunks not loading in Forge (online server)

[johnwayneclutch]

Hello, I'm trying to play on an online server with Forge 1.12.2 yet when I log in the blocks do not load unless I collide with them and only those that I come in contact with actually show. I did some looking online and people have said F3+A should force reload chunks but it does nothing for me. I also made sure my Java was up to date. I closed my Minecraft and downloaded the latest forge release and tested to see if I was just using an outdated one, no change. I then logged into the server using the standard 1.12.2 and the world loads just fine. This issue only happens on this server in particular and doesn't happen on any others nor does it happen in single player. 
Here is my Debug Log:

Try removing shaders mod and possibly optifine.

You think that could really be the issue? I've been on the server before with optifine and the shader with no issues. I'll give it a try and let you know.

[johnwayneclutch]

Alrighty, I removed Optifine and now everything loads just. Does that mean I was using an outdated version?

[DaemonUmbra]

Can't exactly speak for Optifine, dev tries to improve MC's rendering engine but it comes with its own bugs and doesn't always work.

Okay. I'll try to see if an up to date version will work. If not I'll just have to deal with no shader sadly. Thank you very much!

Hey I'm running Forge Minecraft Server 1.15.2-31.1.0. I have Oh the Biomes You'll Go installed on the server and 1.5G allocated as it's max usage. I installed the mod after world creation so I tried to force new world generation and walk until I see new biomes, but instead I get missing chunks in hills. F3+A does nothing. Any ideas?
