heroku run rake db:migrate Error connecting to dyno

Question

I am new on ruby on rails. and am trying to deploy my application from my local system to heroku, but when i run heroku run rake db:migrate, i get this error msg: Running rake db:migrate attached to terminal... up, run.7855 !
! Error connecting to dyno, see https://devcenter.heroku.com/articles/one-off-dynos#timeout-awaiting-process

I've followed the link to the site but i didn't understand what was said there. Please any help as to how deploy it successfully will be much appreciated. Thank you

Seems like your have no access to rendezvous.runtime.heroku.com:5000

Ask your system administrators or internet service provider to allow this address and port for you

This problem solution already described at https://devcenter.heroku.com/articles/one-off-dynos#timeout-awaiting-process, but I didn't understand at once too :)

You can check access to necessary resource by telnet rendezvous.runtime.heroku.com 5000 command

Update: Recently I encountered with problem when rendezvous.runtime.heroku.com:5000 is accessible but heroku run ... command doesn't work. In this case command must be modified to heroku run:detached ...

It helped me, but interactive utilities like bash will not work because of output will be available only in logs
