One of our tentacles suddenly stopped communicating yesterday, and nothing I do seems to be able to get it to connect again
I’ve
restarted,
re-installed,
removed and re-added the tentacle,
checked the firewall settings,
restarted the server twice.
Nothing has changed, I have no idea why this tentacle has suddenly stopped communicating.
If I access the port in a browser; Octopus Tentacle configured successfully If you can view this page, your Octopus Tentacle is configured and ready to accept deployment commands.
When I do a health check on our Octopus Cloud Sever for the Tentacle; An error occurred when sending a request to 'https://***.***.***.***:10933/', before the request could begin: The client was unable to establish the initial connection within the timeout 00:01:00. The client was unable to establish the initial connection within the timeout 00:01:00.
The first place to start though would be to check the OctopusTentacle.txt log file on the tentacle machine, the default location is C:\Octopus\Logs\. If you can attach the most recent log file there I can take a look for any issues.
When you checked the tentacle port in the browser, was this from a browser on the Octopus Server machine? If not, give that a try too.
System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. —> System.ComponentModel.Win32Exception: An unknown error occurred while processing the certificate
I should’ve checked the logs thanx, this appears to be the error in the logs at the moment.
The Octopus Server is a Cloud Server, so I’m unable to check from that location
You mention that this is only affecting one of your tentacles?
It would be worth running IISCrypto on one of the working tentacle machines and this machine and see if there are any differences in the configuration.
Hey Paul,
That did not resolve the problem.
I’ve since used “tentacle new-certificate”, copied the new Thumbprint onto the Octopus Server Instance and rerun the Health Check
That also did nothing, still the same error.
I’ve checked and in the logs, the latest is (There appears to be no connection attempt);

I’ve stopped the existing tentacle, installed a new one, copied the thumbprint into the instance on the Octopus Server and rerun the health check.
This has also not resolved the issue.

You mentioned that your using our Cloud instance, are you able to provide the instance name for me?
We are currently in the process of migrating instances to a new hosted platform and I’m wondering if this could have coincided with this issue in some way.
