Sometimes it works, sometimes it doesn’t. It’s simply really annoying to have to close the current tab and open a new tab in order to continue browsing the topics.
I get this error somewhat frequently, and I’ve been able to reproduce it many times. The way I’ve been able to do so is by opening multiple topics, quickly grabbing the built-in discourse scroll bar, and scrolling all the way down. After like 7-10 or so times, I get that error to no avail.
Is it possible that you are scrolling through and reading many topics too quickly?
