Unknown identity type HTTP/1.1

Hey team,

I’m trying to setup a polling tentacle that communicates with an Octopus Server that sits behind an AWS Application Load Balancer.

The tentacle is able to authenticate and even register itself in the Octopus server but as soon as the wizard finishes and the service starts, it throws the following error:

Halibut.Transport.Protocol.ProtocolException: Unable to process remote identity; unknown identity type: 'HTTP/1.1'

The wizard finishes successfully (it is possible to see the new tentacle registered in the Octopus Server) but from this point, the Tentacle is not able to reach the Octopus server. Analyzing the OctopusTentacle.log it shows multiple errors like the following one:

From the Tentacle box I’m able to reach the Octopus server on port 10943 (https://octopus.domain.com:10943) and also the login page.

Is there any way that I can increase the logging level on the Tentacle to debug the connectivity and identify the root cause?

Thanks in advance.
Bruno.

Hi Bruno,

Thanks for getting in touch! You can certainly change the logging level on the Tentacle by updating the minlevel attribute in your tentacle.exe.nlog file (this is located in C:\Program Files\Octopus Deploy\Tentacle in standard installations) to Trace (set to Info by default). This process is also outlined in the following doc page. :slight_smile:

I hope this helps! Don’t hesitate to reach out if you have any further questions or concerns moving forward.

Best regards,

Kenny

Hey Kenny,

thanks for that. Unfortunately increasing the log level to TRACE didn’t make much difference in the amount of information the logs were showing.

Would you be able to help with the error we’re getting from the Tentacle?

Thanks.
Bruno.

Hi Bruno,

Thanks for following up, and I’m sorry to hear the trace logging didn’t help with troubleshooting this error. Looking a little closer at it, I suspect the issue could be due to another service using port 10943. Could that be the possible cause for you?

I hope this helps! Let me know how you go or if you have any further questions.

Best regards,

Kenny

Hey Kenneth,

sorry for the delay in replying back to you.

There’s no other service running on the server. The Octopus server is listening to 80 and 10943 - and the ALB is allowing 80, 443 and 10943. Also, I’m able to reach 10943 using both ALB address and the server’s IP address.
The issue only happens after registering a new tentacle.

Thanks,
Bruno.
