I’m experiencing a rather strange issue. I’m running an OpenZiti controller and router version 1.8.0-pre4 with the latest client. On my macOS clients, I get “connection refused” to some services unless I stop the edge tunnel on the macOS client and run nc -vc hostname.tld port at the exact moment t…

OpenZiti 1.8.0-pre5 Control Channel Stuck in "reconnecting" State - Regression Bug Critical Issue Summary After upgrading from 1.6.12 to 1.8.0-pre5, router-controller control channel is permanently stuck in "reconnecting" state despite correct network configuration, causing all circuit creation to f…

There's definitely something unusual happening in your setup. I don't think it's the control channel, though. The reason you're seeing 'reconnecting' in the log messages is because that's the type of channel implementation. The router -> controller channel uses a 'reconnecting' implementation. It a…

Hi @plorenz , Thank you for the clarification about the "reconnecting" channel implementation - that makes sense now! I was misinterpreting the context field. Stack Dumps Collected I've collected stack dumps as requested: **Files:** - `controller-stackdump-20260109-183851.txt` (32KB) - `router-…

Hello, thank you for getting and sending over the stack dumps. Unfortunately, they don't show any routing activity. This should manifest in the controller stack dump as one or more calls to Network.CreateCircuit - ziti/controller/network/network.go at v1.8.0-pre5 · openziti/ziti · GitHub On the ro…

Thanks Paul :slight_smile: I captured stack dumps every 2 seconds for 60 seconds (30 captures total) while triggering client connection attempts controller-6-redacted.txt (82.0 KB) router-9.txt (126.3 KB)

I think there's overlap. The invalid session problem seems likely to be a c-sdk issue, as it's not refreshing sessions after they become invalid. The c-sdk folks are digging into that issue. I'm digging into this because of the server side timeouts, which seem suspicious. Paul

Leaving this response here, but there's a more relevant follow-up below [image] msbusk: hanks Paul :slight_smile: I captured stack dumps every 2 seconds for 60 seconds (30 captures total) while triggering client connection attempts Hi @msbusk I looked at the stacks you sent but didn't find …

@msbusk I took another look through your previous messages to see if I'd missing anything, and I had. The timeout you message you got was from line 139 of route.go, which is here: func (rh *routeHandler) fail(msg *channel.Message, attempt int, route *ctrl_pb.Route, err error, errorHeader byte, log…

Hi Paul, Thanks for the detailed walkthrough — that makes a lot of sense, and it does point to the hosting SDK not responding to the dial request. That would match what we are see, the strange thing is we have other installation with version 1.6.12 running with same SDK versions without problem usi…
