You need to remove the previously stored host key from known_hosts but the CLI can assist you. Run knownhosts to print all the host keys and then knownhosts --del <index> to remove specific ones. If connecting locally, it will be a host key for localhost.
netopeer2-server
You have another application running that is bound on the same port 830. Most likely another instance of netopeer2-server is running in background so terminate it.
I have a problem with server and cli not connecting on my ubuntu, what should I do to fix it, I first did a reinstall of sysrepo and netopeer2 (make, make install), but it still doesn't work! I tried to re-execute both merge_hostkey.sh and merge_config.sh files, and after successful execution it still didn't solve the problem of not connecting. I read the content of the two files, it mainly uses sysrepocfg to configure the environment, so I also executed it separately, here it is：
Command line in merge_config.sh root@ubuntu:/usr/local/share/netopeer2# sysrepocfg -X -x "/ietf-netconf-server:netconf-server/listen/endpoint[1]/name | /ietf-netconf-server:netconf-server/call-home/netconf-client[1]/name" `
`
Command line in merge_hostkey.sh root@ubuntu:/usr/local/share/netopeer2# sysrepocfg -X -x "/ietf-keystore:keystore/asymmetric-keys/asymmetric-key[name='genkey']/name" `
`
