Ssh port blocked

Technical Help
1

I have hosted a ubuntu machine on lambda labs .
I think by mistake I have blocked the SSH 22 port due to firewall misconfiguration.
Now I could not SSH into that machine.

Is there anyway I can enable SSH port on the ubuntu server?

Thanks

Probably the only way is to rebuild the server if you don’t have a VNC access…

Are you able to access your instance using Jupyter Notebook?
