The contained exception was: Invalid link mode 0 in link request proof

Since i upgrade to nomadnet 0.7.0 When I try to connect to a node or send a lxmf message, try to load but nothing happen. In the log , I have these 2 errors

2025-05-22 18:12:06] [Error] An error ocurred while validating link request proof on . │ │[2025-05-22 18:12:06] [Error] The contained exception was: Invalid link mode 0 in link request proof

I try another software Retibbs and I was able to connect and use the BBS. I don't think is the rns the problem since I upgrade it at the same time than nomadnet

System Information

• Linux MintOS 22.10
• Python version 3.12.3
• nomadnet 7
• rns 0.9.6
• lxmf 0.7.1

This error occurs because the node you are connecting to is running an old version of RNS, that doesn't support the new AES-256 link and packet modes, which is now used by default.

Support for these modes were added in version 0.9.5, but apparently a lot of people haven't upgraded yet.

The fix here is to update nomadnet, or at least just RNS on nodes running old versions.
