Hi, sorry for the late response. If this is still happening, can you describe the problem in more detail and provide a link to the Repl? And can you confirm that you are maintaining a sufficient cycles balance to keep your deployment up? If your cycles balance gets too low to pay for your tier then your reserved VM deployment will be suspended.
