Hello community, I recently upgraded from traefik version 20.8.0 and hub-agent version 1.2.1. However, after the upgrade, the deployment of hub-agent-dev-portal pods kept restarting after version to version 1.4.0. Although Lens Dashboard indicated a successful upgrade, I proceeded with upgrading to version 1.5.7. The 4 pods of hub-agent-dev-portal are restarting, I tried to delete them but the pods keep restarting. Unfortunately, I could only upgrade traefik to version 21.0.0, and upon attempting to upgrade to version 21.1.0, I received an error message: "Error: UPGRADE FAILED: cannot patch "traefik-dashboard" with kind IngressRoute: Internal error occurred: failed calling webhook "hub-agent.hub-agent.svc": failed to call webhook: Post "[https://hub-agent-controller.hub-agent.svc:443/ingress?timeout=10s](https://hub-agent-controller.hub-agent.svc/ingress?timeout=10s)": EOF" I am not sure how to resolve this issue. Should I delete the traefik, hub-agent and reinstall it? I have also attempted to rollback, but I received a "Bad Request" message. I appreciate any guidance or suggestions you may have. Thank you, Ranganath. ---

Hi @Exnadella ! Could you please: - Tell us the exact versions of Traefik Proxy and Traefik Hub and the Helm chart you're running right now? - Share your configuration? Thank you! ---

Hi @svx, Thank you for looking into the issue. Over the weekend, I deleted the entire hub-agent and all my configurations from the traefik dashboard. I then reinstalled the latest versions of hub-agent (v1.4.2) and traefik proxy (traefik v2.9.10) using helm versions 1.5.7 and 22.1.0, respectively. I also tried deleting the validatingwebhookconfigurations & mutatingwebhookconfigurations as suggested in one of the blogs, but I couldn't find either of them. However, even though traefik and hub-agent were successfully deployed, the problem remains the same. Since then I am facing an issue where a loadbalancer service that I published is not published, even though one of the service has been published. Both the services were previously working and reachable before the upgrade. ---

Hi @Exnadella, could you run both, Traefik and The Hub Agent in DEBUG mode and post the output? Could you also share an example service configuration (without private settings) Thanks! ---

Hi @svx, How to run the Helm in debug mode? I can export multiple logs for tunnel, controller, dev-portal, auth-server and traefik will that be sufficient? ---

Hey @Exnadella, For Traefik Hub: If you use the [default chart](https://github.com/traefik/hub-helm-chart/blob/master/hub-agent/values.yaml), the log level is already set to DEBUG, so just posting/exporting them will be enough. If you changed the level, you have to set them the level to `debug` and re-deploy. For Traefik: You can adjust the level [in the chart](https://github.com/traefik/traefik-helm-chart/blob/master/traefik/values.yaml#L236) and re-deploy. ---

Hi @svx, I have successfully managed to publish all my services. However, I faced a challenge when I tried to delete all the traefik-hub published services on the Hub-Dashboard. One service was stuck with the old deployment and it was causing an issue. To resolve the problem, I deleted and re-deployed the problematic deployment, and then republished it. Nonetheless, I am still facing an issue with the API-server not being visible on the Traefik-Hub Dashboard.
