Hey everyone, hope you're all surviving the endless platform updates out there. I swear, between CRM patches and OS updates, it feels like my life is just one long, complicated migration project 😅
So, here's my latest saga. I've been running the iboss Windows collector (version 7.2.3.200) pretty solidly for our RevOps team's security compliance. Everything was humming along until the latest round of Windows 10/11 patches (I'm looking at you, KB5035849 and KB5035853). After the mandatory reboot, the collector service just... refuses to start. It's stuck in a "Starting" loop in Services, and the local system tray app claims it can't establish a connection to the cloud gateway. The event log is throwing a couple of vague errors about "failure to initialize secure channel."
Before I spend my entire weekend deep-diving into this, I wanted to check if I'm flying solo here or if this is a known party.
**What I've tried so far (the usual migration war-story checklist):**
* Complete uninstall (using the iboss cleanup tool) → fresh reinstall. No dice.
* Verified all the usual suspects: firewall rules intact, DNS resolving correctly, no proxy conflicts (we use a direct connection).
* Tried rolling back the OS patches, which *did* get the collector working again, but our IT security policy obviously doesn't allow that as a permanent fix.
* Opened a ticket with iboss support, but I'm still in the queue.
This is giving me flashbacks to that time a Salesforce Marketing Cloud connector update broke our HubSpot sync for two days. The pain is real!
**My current environment:**
* Windows 11 23H2 (also seen it on a few Win10 22H2 machines)
* iboss Collector v7.2.3.200
* Latest OS security updates as of March 2024
Has anyone else in the community stumbled into this particular pothole after the recent patches? If you found a workaround or got a whisper from support, you'd be saving my sanity. I'm especially curious if it's something simple like a specific certificate needing a refresh or a changed local policy.
Fingers crossed this is a quick fix and not another platform-induced "vacation" into troubleshooting hell.
Hopefully last migration,
You're definitely not alone on this one. We saw the same pattern across about two dozen endpoints after those patches were applied. The "failure to initialize secure channel" error seems to be a TLS handshake issue between the collector and the gateway, likely triggered by a change in the OS's cryptography stack.
We had some success, not with a full reinstall, but by forcing a specific protocol. You might try adding `-TLS12Only` to the collector service's startup parameters as a temporary workaround. It bypasses the negotiation that's failing. Also, check if your security software is suddenly intercepting or inspecting the collector's outbound traffic on a new port; that was the culprit for us in a few cases.
Have you opened a ticket with iboss support? They were aware of it when I called, but their official patch is still in validation.
Ah, the classic post-patch TLS handshake meltdown - I feel your pain! Your checklist is solid, but those OS-level crypto updates can be truly sneaky.
Beyond the TLS flag workaround, have you checked if the patch reset the Windows Schannel security settings? I've seen similar "secure channel" errors when a patch unexpectedly enables or disables specific cipher suites. You could run `Get-TlsCipherSuite` in PowerShell to see if the list got shuffled and compare it to a known-good machine.
Also, double-check the system certificates store (both machine and user). A corrupted or missing root CA cert after an update could be the silent killer here, even if DNS and firewalls look perfect. That one's cost me hours before.
Data nerd out
Yeah, your checklist is the right place to start. Since you've already done the reinstall and checked the network basics, the event log error is the key.
The "secure channel" failure is almost always a crypto mismatch now. Before you add the TLS flag, check the local machine's certificate store for the iboss root CA. I've had updates silently deprecate or move those.
Also, quick sanity check - has your security team rolled out any new endpoint policy that might be applying to services post-update? Sometimes those patches trigger a re-evaluation that blocks the collector's process.
terraform and chill
The certificate store check is a solid shout, but let me add a wrinkle. Even if the root CA is present, I've seen these patches silently change the permissions on the machine store's private key folder, preventing the collector's service account from reading the cert it needs. Running `certutil -store My` will list them, but you need to get into `mmc.exe` and manually check the security tab on the specific certificate to be sure.
Also, your point about endpoint policy re-evaluation is dead on. It's not just new policies, it's that the patch often resets the "last evaluated" timestamp and forces a sudden, aggressive re-application of existing ones. If you've got anything blocking unsigned drivers or restricting process creation, that could now be catching the collector's sub-processes where it didn't before.
