Please Read and Confirm The Following

• I have confirmed this bug can be replicated without the use of Optifine.
• I have confirmed this bug is on the most recently supported version of Minecraft.
• I have confirmed the details provided in this report are concise as possible and does not contained vague information (ie. Versions are properly recorded, answers to questions are clear).
• I have confirmed this issue is unique and has not been reported already.
• If playing on a modpack, I have reported this issue to their issue tracker already.

Go ahead, install Aether on your default Forge client, then try to login to a vanilla server. It won't work.

Please do more research before you report issues when you have not actually proven them, just because you assume it exists, and listen to developers who actually know what they're talking about with their mods. We have an official server that has not had this issue, Modding Legacy has an Aether server that has not had this issue, and the Twilight Forest developers also have a modpack server that has Aether installed and has not had this issue. The issue only occurred when trying to join servers using an incompatible client (as you have done here). The Aether mod has also been tested by the Essential developers themselves with the Essential mod. Closing this issue now.

I have actually removed a couple others due to them causing weird log spam type issues and reported one of them to their respective mod author, others caused various exit codes 1 and -1 respective. those are all either downgraded to working versions or disabled altogether until a fix can be implemented into a future update.

Does everything work fine without Aether included? Also please do not list every beta version as your version, I need to know what specific version is being used by the clients and server.

reason I listed them all is cause after each launch and connection test, I downgraded it starting with the latest which is beta 4 just to show that the issue persisted through all the updates. and yes everything works just fine with the aether disabled.

Have you also tried testing removing other mods but not Aether?

im now running the test with just essentials mod, jade, jei, neat, the one probe and the aether enabled.

i will now commence a minimal instance test

I mean have you narrowed down confirming whether this issue is just caused by Aether or if it's caused by an interaction between the Aether and a specific other mod by removing mods until either the error went away or the only mod left was the Aether?

I dont have access to this particular servers logs at all. seeing as the address for it is literally test.prisonfun.com which I can connect to just fine without the aether as from Ive gather all over the web is just basically a connection test server in which a lot of people just like to horse around on

I'm just gonna chime in and say that this is usually caused by a different mod version being used between the client and server. The game is confused because things aren't matching up.

with just those enabled, issue still occured. now proceeding to remove essential and see what happens

error occured again, now removing neat

and the error continues, now removing the one probe

now removing jade as the error occured once more

Why have Structure Gel enabled if you disabled Blue Skies?

now its just the aether by itself

Could you now please provide the logs from both the server during the time of join and the client during the time of join when this error occurs?

Which sounds like it is the case if you are trying to join a server that doesn't even have the mod installed.

I'm just gonna chime in and say that this is usually caused by a different mod version being used between the client and server. The game is confused because things aren't matching up.

well this particular server will allow modded clients to login but forces the mods to a disabled state

That's simply not how it works. Forge still has mods loaded on your client, so the game's code, registered items and entities, and etc. will all be different. The server can NOT ever change the code on your machine.

nevertheless i am still abled to connect to the server with the aether disabled.

also here are the logs for just the ather enabled

https://gist.github.com/Devilswarchild/ea416928256609d5699a085b5479dbe4

yes, same issue

Then have you tried hosting with the Essential mod, with only Aether installed?

Have you actually tried to test joining a server that has the Aether, with the Aether mod?

no I haven't actually cause I dont currently know of one, due to the fact that my modpack contains the essential mod which kinda negates the need for a dedicated server

well I can't give you the other end of the connection because I don't have anyone to help me with this. Im a modpack creator who is doing all of this solo

Then where did the connection error you gave in the post come from?

Then could you give the logs of the Essential "server" (the host), and the client trying to join that is getting the error?

the essential mod doesnt generate any logs to my knowledge

but let me double check that

nope, no logs in its folder

The Essential mod should be hosting from your client, and the client always generates logs.

yes, and I have provided you with all the logs that I can generate. but ill run it again with the aether and essential as the only enabled mods
gimme just a few minutes

Yes, and the previous logs you provided me had 100 other mods installed. Please provide me the logs but without those mods and only the Aether.

That's simply not how it works. Forge still has mods loaded on your client, so the game's code, registered items and entities, and etc. will all be different. The server can NOT ever change the code on your machine.

nevertheless i am still abled to connect to the server with the aether disabled.

also here are the logs for just the ather enabled

https://gist.github.com/Devilswarchild/ea416928256609d5699a085b5479dbe4

the link above is with just the aether

That is only the logs from one end of the connection. I already said I need logs from both ends of the connection.

I know that, that doesn't answer my question though.

however, if the test server I connect to is throwing the io.netty.handler error then either me or if I manage to get someoone to connect to would also throw the same error due to it being a multiplayer connection

That is because, as stated before, the connection server does not have Aether installed.

test.prisonfun.com is the server address I use to test network related issues with my modpack. that address was obtained from several troubleshooting guides across the web which has been very reliable to detect networking issues. and all the issues I've ever had with my modpack have all been the same exact error across all the mc versions of my modpack. I dont not own or have access to any of the files associated with the server.

yes, same issue

Then how did you receive the same connection error from Essential if you only tried ever joining this server?

I was simply referring to the fact that essential does ,if I can word this correctly in a way that'll help with the understanding it of it, is replaces/improves the open to lan feature by making the "host" pc act as a dedicated server without the actual need of a dedicated server if that makes any sense

So you are not actually sure whether there is an issue with either the Aether or your modpack.

and I also tried upgrading forge from .57 to .66 and the same issue occurs there which leads me to believe that, hear me out, its quite possible that a line of code could have gotten overlooked or possibly had a typo but what do I know. Im not a coder

That is because, as stated before, the connection server does not have Aether installed.

i can assure that isnt the case because an earlier version of my modpack also has the aether installed and the server didnt and I was able to connect just fine

and by earlier version, I mean of course a version of my modpack on an earlier version of minecraft

Not all mods are guaranteed to be able to connect with vanilla servers, because its a vanilla server. It cannot account for every change a mod makes which may make them incompatible. I don't even understand at this point why it matters whether you can connect to this vanilla server or not with your modpack.

bc If I cant connect to this test server then none of the players using this version of my modpack are going to be able to connect with their friends. (if any of them have any)

And how are you sure of this if you have not tested joining a server that has the modpack on it with a client that has the modpack?

bc the only person I could potentially try to have help me with this is currently engaged in other activities and wont be available for quite some time

like an undisclosed amount of time

ergo I dont know if or when they will be available.

oh no, im very sure. if it happens one place, it happens on the other,

🍿

ok i managed to get ahold of this person to do an essentials mod test with the aether. she was able to connect just fine. so my apologies. however tis particular instance doesnt always happen. more often then not with my mopack when I get the error one place it always happens in the other place. this is probably the 1% where there is actually no issue using a (insert mod name here) with essentials.
