I have used the load balancer with session affinity (by Cloudflare cookie only) for several months now and it worked well. Today I upgraded my browser to Chrome 80.0 (nothing else changed) and now it is not working anymore. I can clearly see that the server changes when I hit the refresh button.
Strange enough, on another computer (Mac + Chrome 80), I could not observe the issue. However, I am not the only one since some of my users complained that the site does not work as expected (due to that issue).
Does anybody experience something similar?
