Sometimes, when attempting to transfer data from inside your VRW environment to or from the Hábrók HPC cluster using MobaXterm, the transfer is registered, but the progress bar stays at 0% and the transfer never starts. There is an easy workaround to resolve this issue described in the steps below.

1. If you are already signed into Hábrók, the first step is to close the connection. To do so, type exit into the terminal, then press the enter button twice.
2. Right click the recorded session, then select Edit session.
3. Navigate the the Advanced SSH settings, and change the transfer protocol to SCP (enhanced speed).
4. Confirm your changes, then log back into HPC by double-clicking the session.
5. Log back out of Hábrók without doing anything else. To do so, type exit into the terminal, then press the enter button twice.
6. Repeat steps 2-4, but change to transfer protocol back to SFTP protocol.
7. Log back into Hábrók.
8. Your transfer should now work.
