Mosh connection issues (custom port range)

Hello,

I might be doing something wrong, but some time ago mosh connections started throwing this error:
```
NoMoshServerArgs - Did not find mosh server startup message. (Have you installed mosh on your server?)
Use mosh1 for the deprecated (previous) mosh version.
```
At the same time ssh2 stopped working too.

Mosh1 and ssh continue to work.

Ssh2 -vvv shows this in debug messages:
```
SSHSession:DEBUG:Attempting authentication with publickey.
SSHSession:DEBUG:Authentication failed
```

Ssh -vvv shows a lot of debug, but among others I can see this:
```
ssh_userauth_agent: Trying identity id_rsa
ssh_key_algorithm_allowed: Checking rsa-sha2-512 with list
ssh_key_algorithm_allowed: Checking rsa-sha2-512 with list

```

Am I doing something wrong? :-)

Please and thank you!
