We're using Traefik v2.10.x(used Traefik Proxy from Azure Marketplace) and we just added these on the annotations of the service and basically it works most of the time:
traefik.ingress.kubernetes.io/service.sticky.cookie: "true"
traefik.ingress.kubernetes.io/service.sticky.cookie.name: signalr sticky
traefik.ingress.kubernetes.io/service.sticky.cookie.secure: “true"
But sometimes, the connection fails to reconnect after a while if there are multiple instances of the SignalR server application. Feels like it is related to the sticky cookie expiring or something. I found MaxAge but it seems only exists in the latest version and not in the version we're using, which is v2.10.1. And probably I'm looking at the wrong configuration.
Any idea on how to fix this issue? Thanks!
