Cloudflare Load Balancer - Session Stickyness - Not working today!!
What steps have you taken to resolve the issue?
Hey together,
we and our customers are using Cloudflare Load Balancer with Session Stickyness set to Cloudflare Cookie with ip fallback. We have a pool of 4 hosts in the background.
Requests from outside of Cloudflare to the Load Balancer Hostname are not sticky! They are freely jumping between the hosts. We have those issues since a couple of hours and we had to reduce our host count to one host in the pool weight configuration. So our users now have a slower application but they can work.
I was not able to open a ticket at the moment so i post that here… We need a fix @Cloudflare!!!
We now had to change the DNS entries because there was no help from cloudflare.
The load balancer with problems is now available here: www-cflb.choice-erp.de
Same issue: Session Affinity is not working. Freely jumping between the 4 hosts.
To give the Cloudflare team more information about the situation:
Here are two cf-ray IDs that were made from the same client but got to different hosts even the _cflb cookie stayed the same and the session affinity should have kicked in but id´t didn´t:
OK thanks. @ikmal@WalshyMVP What was the cause and how do you mitigate this issue in the future. We now had the issue for more than 24 hours and had to reroute traffic to another (competitor) load balancer. We need to convince our customers to get them back to cloudflare and they will ask those questions.
