Connecting to Tensorboard via SSH port forwarding fails

I’m trying to connect to Tensorboard running on the server via SSH port forwarding. The port is 6006. The ssh invocation from client is ssh [email protected] -L 6006:IPv4:6006 . Here IPv4 is the IP address of the Paperspace server. This actually worked for a while. But not anymore. Connection refused. What am I missing?

Hi @cg95110 Welcome to the forum! Did you attach a public IP to your VM? If so, the next step would be to check the system firewall for rules that would be blocking this traffic. Assuming you have a public IP, we do not block any inbound/outbound traffic or ports.
