Matrix Synapse is crashing and rebooting

[jfrere]

On my Cloudron dashboard, I notice the Matrix app disappearing and reappearing. It seems like the app is crashing and restarting, but nothing is showing up in the logs so far.

Do you mean it goes from "running" to "starting" in the dashboard? If the app would restart something should show up in the app logs about the restarting. To make sure logging works, maybe manually start/stop the app while you have the logviewer for the app open.

Not sure if it's related to Matrix. Got strange behaviour here.

Seems like it can't reach the appstore api server, causing various side-effects. Can you run cloudron-support --troubleshoot to get an overview?

This looks good.

Can you also test both commands below from your server:

curl -4 https://api.cloudron.io/api/v1/apps
curl -6 https://api.cloudron.io/api/v1/apps

[jfrere]

curl -4 worked

So something is not working with the ipv6 routing then. Which VPS provider is this?

[jfrere]

We don't use ipv6, only ipv4

Fixed. Was a clone of the actual VM running at the same time, on the same IP.
The clone didn't have Matrix Synapse installed. That's why the dashboard was displaying the app, then it disappeared on page reload.

oh glad you found that!

Yes, 1 hour of investigation for that... sorry for the inconvenience.
