Event Viewer Error

Hi Octopus Support,

I have noticed on one of the machines that my tentacle (version 2.36) i have noticed quite a considerable amount of Errors within Event Viewer. Any reason why there are soo many errors.

2014-06-25 19:48:40.6857 ERROR Unhandled error when processing request from client
System.IO.IOException: The handshake failed due to an unexpected packet format.

Hi Jesse,

Thanks for getting in touch!
Yeah the Event Viewer was pretty much recording all the errors.
We fixed it with this issue: https://github.com/OctopusDeploy/Issues/issues/860 for version 2.4.8
They are now written to the logs, but not the even viewer unless fatal.
Mostly commonly port scanners or incorrect setup issues cause tentacle errors like the ones below, and in some cloud services that can’t be avoided.

Hope that helps!


Hi Vanessa,

Thanks, I’ll make sure I’ll upgrade in the coming weeks. Thanks for the quick reply! :slight_smile:
