Metabase on Heroku stopped working

I deployed a metabase package to Heroku and successfully created dashboards and reports.
It worked for a while but now when I start the app on Heroku I get error.
Looking at the log files I see errors like this:

at=error code=H10 desc=“App crashed” method=GET path="/" request_id=a437f734-7d90-47e8-8920-716a81755029 fwd=“” dyno= connect= service= status=503 bytes= protocol=https

please help

What does the log file in Metabase reveal? The log entry you share looks like something from outside Metabase (I’m guessing heroku) basically just telling you a 503 web server error - but doesn’t give any indication of why Metabase can’t respond.

Recently others have indicated here they needed to up the resources (Dyno size?) to succesfully run with newer versions of Metabase. So failing to get to the logs etc. you might just try feeding more memory etc. and see if that helps. (Sorry no experience myself with heroku so can’t really give more specific hints on that)

Most probably it is a memory issue. Try to increase it and share the log if it persists.
