Updated the site meanwhile and pushed an automatic update to tackle the exceptions reported above. Let me know if it's working for you :)
I re-downloaded the DLL from the Rust:IO site and restarted my server. Still getting the same error:
Rust:IO: Failed checking for update (Exception: update failed: Could not resolve type with token 0100006c (from typeref, class/assembly Rust.Protocol, Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null))
Make sure that you are running the latest version of the Rust:IO Oxide extension!
