Java Config URL & Unexpected Js5 server response: CLIENT_OUT_OF_DATE (RSProx & Alter)

[Grown]

Hello,
Unfortunately I am not much of a programmer by any means. Although thought it would be fun to code a OSRS based rsps for my own fun.

I am using Alter and RSProx. Now I will not lie, I struggled to get to the point I am at right now. My current issue is when I select my appointed 'server' using Native the client will launch but I will get the following error.

Spoiler for Unexpected JS5 server response: CLIENT OUT OF DATE:

I have tried for hours now to research why this is the case. From my understanding it has something to with the client not able to load the cache, or able to find the server, something to that regard.
What I believe my problem is, I do not have the proxy-targets.yml set properly.

config:
- id: 1
 name: Test
 jav_config_url: https://client.blurite.io/jav_local_227.ws
 varp_count: 5000
 revision: 227.3
 modulus: b9f8316db0ebe47d07db3b058d90631f0fbd437645b4d6d4f9b52e078882fe4cf68b1379980376f3fd331bb78a17757de342b2310b484a91beaf897e1695ce3d032d88d0c5b6e6d643857cf72dffeac637972ed078f5d4ff219e5b4ccf7c6b9377188fafdad8bdb977599a7c2a4ba405cce520f17fa05f1aefb18d429b6b2621

I believe what I need to do establish my own jav_config_url. "The URL to the jav_config that will be used to load initial world and world list." Now I tried to figure out how to do this, but I cannot find any tutorials, or info on how to properly do this. To be completely honest, I don't understand how the jav_config works.

The jav_local_227.ws file has the following parameters or code (Not sure if that's the right terminology or not )

Anyway, that's where I am at. Not looking for any free hand outs or anything, just need some direction. If you guys have any tutorials you would recommend I read into please feel free to link me them. Thank you, I will provide brief video below of my progress.

The client version needs to match whatever version your server is expecting, shouldn't be anything to do with the cache. Why are you using rsprox anyway, is it suggested to use that as a client for alter?

 

[Advocatus]

If ur using current alter its 228 not 227.

As others have said, you're just on the wrong revision.
You can check what revision alter is using by checking the dependency on RSProt: https://github.com/AlterRSPS/Alter/blob/main/gradle/libs.versions.toml#L69

As for what client versions are valid to use (the `revision: 227.3` in the yaml config), you can visit https://archive.lostcity.rs/oldschool.runescape.com/native/osrs-win/
Pick the correct major version there that matches the RSProt dependency - subversion is down to you, whichever you prefer, though the latest one typically comes with fixes so that's what I'd recommend.
You also needn't maintain your own jav config, changing the blurite javconfig url will do the trick (e.g. _227 to _228) - I'm maintaining them starting from revision 223. If you wish to do edits, of course host your own.

Thank you Kris.
Appreciate the guidance, and access to RSProx.

Thank you Corey, was able to resolve the problem thanks to you and Kris.

Originally Alter recommended using Devious as the client but apparently it has been used for malicious activities.
In Alter's updated thread he recommends:


If there is a better way to utilize a client? Should I not use RSProx? I'm trying to do everything properly without taking any shortcuts, and learning the right way.

Thank you.
