**What type of hardware are you using** : VPS bought online
**What YunoHost version are you running** : 12.0.11
**What app is this about** : Synapse
### Describe your issue
After upgrading to Yunohost 12, Synapse service is the only app that is not running. The service start error log is below. There is a hint if the synapse server is running and accepting TCP/IP connections on port 5432, but I am not sure how to test that.
This might be related to port 8448 is not reachable, but I am not sure. Therefore that is in another post: [Port 8448 not reachable from outside](https://forum.yunohost.org/t/port-8448-not-reachable-from-outside/35931)
Thanks in advance!

5432 is the port on which PostgreSQL should be listening. Is the service up?

Thank you for your response. PostgreSQL is running. Here is diagnostic logfile:

But you’ve mentioned [here](https://forum.yunohost.org/t/howto-repair-postgresql/35922) your psql was dead. Is synapse still broken after you fixed it? What log are you getting when starting Synapse now?

No, PostgreSQL is OK now. Synapse service log is here:

What else can I do to find the reason for this problem?

It now says module Synapse is missing you can try rebuilding venv or force upgrading the app (`sudo yunohost app upgrade synapse -F`)

Before I tried your proposal, I ran the recommended updates including Synapse, successfully.
The Synapse service was running, but different client couldn’t connect. Later on, connection seemed slow, and now everything appears to run.
Since your proposal might have been successful, I will mark it as solution. Thank you very much!
