The app is not working any more.
Also a restart of the app or rollback to a backup does not help.

Error message I see in the App Log:

ERROR: remaining connection slots are reserved for non-replication superuser connections

No changes btw on my side.
Seems ok like a DB thingie?

The log shows it tries:

• Running db migrations
• Sequelize CLI [Node: 12.16.2, CLI: 5.5.1, ORM: 5.22.3]
• Parsed url postgres://XXX
• getting the error from above.

Other services still work.
How can this just happen?

Thx for some helping advice!

@grienauer this looks like the postgres addon ran out of connections in the pool. Maybe an app is occupying too many. To temporarily fix this, just restart the postgres service via the Cloudron dashboard.

Is it possible that you had some frequently restarting app lately? We have seen this error more often now since last release, but I don't have a long-term fix yet.

Services -> Postresql -> Restart should fix this but not sure about the root cause.

@girish works. issue can be set to fixed.
Don't know why this happens. maybe needs some further research…

@grienauer You can set this thread to "solved" yourself.
