Authentication failed because the remote party has closed the transport stream

Hi Team,
So I installed a listening tentacle on one of our environments and trying to establish a connection to the octopus server. The listening tentacle works fine locally as I was able to receive the (successful connection) message when browsing and I have also enable the port (10933) in the windows firewall yet I receive the the following error:

System.IO.IOException: Authentication failed because the remote party has closed the transport stream.

Thanks for the help in advance.

In addition in the communication logs for the deployment target shows:

Hi Nathaniel,

Thanks for getting in touch!

The error messages you are seeing are definitely pointing to an environmental issue with communications from your Octopus Server to your Tentacle. I suspect that there may be a firewall/proxy in between your Server and Tentacle, or there is a TLS mismatch.

For the first issue, are you able to confirm if you can connect from your Octopus Server to your Tentacle by opening a browser and going to http://TentacleAdress:19033 and see if it connects?

If you can also go through the troubleshooting steps outlined here that would also be greatly appreciated.

Thanks Nathaniel, I look forward to hearing from you shortly.

Regards,
Alex
