Hello Jesper,
RSE / Eclipse uses JSch for the SSH communication. As per the JSch homepage http://www.jcraft.com/jsch/ , the following ciphers should be supported:
Key exchange: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521
Cipher: blowfish-cbc,3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-ctr,arcfour,arcfour128,arcfour256
Please check if any of these should be compatible with your host. You could also try checking with a local command-line ssh to see what your host reports (ssh -vvv yourhost).
I'm afraid that I won't be able to help beyond these initial hints. RSE is not really maintained any more. You might try the mailing list https://accounts.eclipse.org/mailing-list/tm-dev but don't expect timely replies.
Good luck,
Martin
