Troubleshooting One-Off Dynos Awaiting Process Timeout Issues

Last updated November 14, 2024

  • Timeout Awaiting Process
  • Additional Reading

The heroku run command opens a connection to Heroku on port 5000. If your local network or ISP is blocking port 5000, or you’re experiencing a connectivity issue, you see an error.

Timeout Awaiting Process

If you’re experiencing a connectivity issue, you see an error similar to:

$ heroku run rails console
Running rails console attached to terminal...
Timeout awaiting process

Test your connection to Heroku by trying to connect directly to rendezvous.runtime.heroku.com on port 5000 using telnet. A successful session looks like:

$ telnet rendezvous.runtime.heroku.com 5000
Trying 50.19.103.36...
Connected to ec2-50-19-103-36.compute-1.amazonaws.com.
Escape character is '^]'.

If you don’t get this output, your computer is blocked from accessing our services. We recommend contacting your IT department, ISP, or firewall manufacturer to move forward with this issue.
