INFO logs are being printed in console. After a while, the “Connected to Node” logs are interrupted and the message “Got notified from Channel as inactive, attempting reconnect.” logs are starting to increase. Eventually all requests timeout.

I tried the QueryServiceConfig.create(0, 12, 1); suggestion but it didn’t work. Anyone have an idea for a solution?
