Client fails to reconnect after server downtime

[camille-bouvy-frequenz]

What happened?

When running tests with the trading app, we tried stopping and restarting the server in order to ensure that the trading app would be able to reconnect once it is back online. However, we observed that the Client was not able to reconnect to the service (even after >5min).

What did you expect instead?

We expected the API Client to connect back to the server once it is back online (most likely in 60secs since it is the keepalive default).

Affected version(s)

v0.3.1

Affected part(s)

Build script, CI, dependencies, etc. (part:tooling)

Extra information

It seemed to work in the past, we're unsure if this could be related to the latest update of the base client (since this is where keepalive is implemented).

Mmm, interesting. If you can find a way to reproduce it consistently can you try with and without keepalive to see if it is related to that (my guess is keepalive should help to re-connect, not the other way around), you can enable and disable keepalive via the connect URL.
