NEO4J Hetionet explorer is not working #38

Closed tsarfaty-lab closed 2 years ago

tsarfaty-lab commented 3 years ago

Hi everyone,

I tried connecting to the NEO4J browser with hetionet from the het.io website (https://neo4j.het.io/browser/) but it seems to be down or not working. Does anyone know any workaround for this? Has the web address changed? The error reads 'The site cannot be reached'. I've tried connecting on different computers, and on different browsers too.

Thank you in advance!

Okay, I SSHed into the instance ssh ubuntu@neo4j.het.io and rebooted. Database is back up.

But first I looked at the logs via tail neo4j-logs/debug.log. Pasting them here in case this helps us diagnose what happened

CC @dongbohu in case these logs mean anything to you!

It seems to be working again! Not sure what happened for the server to not work. Nevertheless, thank you!

I restarted it!

Closing since we now have uptime alerts, see https://github.com/hetio/hetionet/issues/45.
