Resolving Long Poll Reload Issues in Phoenix LiveView

In a production setup using Phoenix 1.7 LiveView, users reported encountering a persistent reload loop every 7 seconds along with an error message. The problem was investigated and found to be related to long polling techniques. Unlike staging, where the setup worked correctly with a single server, the production environment used multiple servers, causing the load balancer to switch between them, leading to the 410 error during session resumption. The solution recommended is to enable distribution for the LongPoll fallback to ensure all nodes are correctly connected and can share session state, similar to WebSockets.
