Q3: Is it possible to set up Oxide 2 for Rust expermental v52 server ?

E: could connect to other hosts.
server.secure is set to false
idk is there other specs that could lead server to think its official(needs steamed rust)

 

I aint talking bout nonsteam. I tested it on steam too. It doesnt work with v52. Playin v52 because friend of mine cannot play better game versions cause it laggs for him. I tested it on steam and on nonsteam rust

 

Okay. Where should i go an ask for any help then? Posted it on kortal too but nobody answers me there. Idk any other forum that is somehow connected with Rust
