Can't connect to friends

[Lunel3829]

Greetings,

My friends and I wanted to try OOT Randomizer at 3. I tried joining their room after following the instructions but I only get these messages.

[01:23:22] Joined room (Custom IP)
[01:23:22] Checking configuration consistency...
[01:23:22] Configuration consistency check failed: Bad hash
[01:23:22] You are not both using the same sync code (perhaps one of you is using an older version?)
[01:23:22] Make sure your sync code is the same and try again.
[01:23:22] Server closed.

My two other friends can connect to each other but only I can't.
Do you know where the problem could be ?

Thanks in advance.

I have the same problem,
Both of us have fresh installs and followed the install guide.
Is there a way to find this "sync code" so we can check if it differs? or could it be the ROM that is at fault? how would i know?
