4 years ago Hi. As the text under "Is this a support request?" in the issue template suggests, it might be better to direct this question to the support team - especially since it's an intermittent network-related issue that might depend on some details of your runtime environment rather than only on the SDK code. All I can say from the point of view of the SDK team is that it would be extremely odd for the SDK not to log anything related to connection attempts, and there are only two log lines shown here - both of which are INFO level, so if you did enable DEBUG level it's unclear what if any debug logging appeared. So whatever is going on, I don't think it is as simple as "it didn't have a timeout."

Describe the bug Establishing initial connection to receive streaming events does not appear to timeout so that it can try again. Restarting the server manually to initiate reconnect allows the SDK to connect successfully. You can see from the logs below that the connection was initialized and 3 days later it was still not connected. FYI debug logging for the SDK was enabled during this time, so I would expect to have seen the "Opened LaunchDarkly stream connection" in the logs or some failure/retrying log message.
To reproduce Initialize SDK for streaming connection (with proxy). Intermittent issue.
Expected behavior If initial connection cannot be established within some timeout interval then close the connection and try again.
