I’ve been following the suggestions here but have had no luck getting streaming to work properly: Streaming not working on Heroku install · Issue #1119 · mastodon/mastodon · GitHub
Basically, I deployed the streaming app as a separate heroku application as suggested. Everything seems to work for the first minute, but then I get the following error because there is no web process:
Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
Afterward, the app crashes and streaming no longer works.
I’ve tried to create a placeholder web server but the PORT is already in use so no luck either.
