"Corrupted MAC on input." when git clone over SSH on VPN from VirtualBox/Ubuntu

Question

Here is the error after I do a git clone in my Virtualbox which is using Ubuntu 16.04.

Corrupted MAC on input. (33872/116798), 2.67 MiB | 5.30 MiB/s
ssh_dispatch_run_fatal: Connection to 10.x.x.x port 2xxxx: message authentication code incorrect
fatal: The remote end hung up unexpectedly
fatal: early EOFs: 30% (35040/116798), 2.67 MiB | 5.30 MiB/s
fatal: index-pack failed

Couple of things to note:

1. Running through VPN (Company use)
2. Virtualbox Network settings:(Allows me to get to any company sites but cannot connect to google)
   • First Adapter: NAT
   • Second Adapter: Host-Only-Adapter 3) Already installed openssh-client -> version 7.2 4)
3. Generated a rsa key and added it to teamforge account settings

Sorry new to virtualbox but could this be a network issue? Could this be a SSH issue?

Yes, looks like an SSH issue. Without details, hard to say what.
