This is strange. My leafbot never tries to connect to the hub bot. Even though I have set it to do so automaticly (.botattr +ghp). But when I tell the leaf bot to connect manually, it links up with no issues (.link hubbot)
I've tried to re-add the hubbot in the leafbot several times.
The same leafbot was able to auto-connect earlier, but after I've deactivated one component in the netbots.tcl script (chanlimit) and rehashed/reloaded and restarted the bot, the problem is here.
