two things i can think of :
a) the shard does not allow unencrypted clients.
iris doesn't support encryption.
you can find out if that is the case by trying to connect with razor+original client and checking the "patch client encryption" checkbox. if you cannot connect like that, the shard requires encryption.
shard admins could change the config to allow that :
for POL shards this can be done by adding the following to uoclient.cfg/pol.cfg
Code:
Listener {
Port 5003
Encryption none
AOSResistances 0
}
not sure how to do it for runuo, but should be possible as well.
b) the shard expects a new/v7+ client version, you can tell iris to behave like that by editing config/shards/yourshard.xml and adding a line :
<string key="gClientVersion">7.0.6.5</string>
