I kept get push notifications that my Heroku server needed updated. I finally decided to go through the process to reploy my server. Everything seems to work as it should until I get to the step where it begins building my server (Step 5 @ https://tonesto7.github.io/echo-speaks-docs/#/docs/installation/configuration/serverConfig). According to the instructions, text should be scrolling through this box as it builds. When I try it, the box remains empty. I’ve let it sit for several minutes, however it seems to be stuck in the building server mode with no result. I’ve even tried deleting my new server and starting all over again with the same results. Anyone run into this or have any suggestions?
You may want to post in the echo speaks thread. That way the developer will be notified of your post and you might get a faster response.

Good idea. Thanks.
