Stringo Lab issue - shipping-metrics-data

Hi,
ssh server1 not working. Facing this issue for the last couple of days.
I have attached few screenshots.

Have you tried restarting the labs through the settings (gear) icon?
I had a similar issue once a while ago.

I tried multiple times, but no luck.

Can you please send me a private message with the lab URL so I can debug it. thank you and sorry for the issue.
