Do you have an ingress or proxy in front of your server? If so, please check its configuration wrt to keep-alives.

[tvalasek]

i can do. i have a question though - something in this release that would trigger this behaviour? I'm using v2.9.5 in exactly same setup and that works just fine.

Can you try :latest and see if you have the same problem?

[tvalasek]

ehm, with :latest I can't even get the workflow-controller pod running

kg po -n argo
NAME                                   READY   STATUS             RESTARTS   AGE
argo-server-698f5b9777-p8npw           1/1     Running            0          6m45s
workflow-controller-8457b7bf64-phnrz   1/1     Running            0          4h5m
workflow-controller-ffd5db46d-l76lb    0/1     CrashLoopBackOff   1          9s

no obvious reason, no logs :(

back to :v2.12.0-rc5 tag, all good:

kg po -n argo
NAME                                   READY   STATUS    RESTARTS   AGE
argo-server-6cff7b6f7b-j2lhn           1/1     Running   0          54s
workflow-controller-8457b7bf64-qb6xc   1/1     Running   0          53s

[alexec]

ah - I should have just said - just run the argocli, not the controller (which is broken)

[tvalasek]

tried following setup

argocli:latest
argoexec:v2.12.0-rc5
workflow-controller:v2.12.0-rc5

Still receiving same error. I tried Chrome as well (just in case), same thing

[alexec]

If you reload the page it goes away?

[tvalasek]

yes
