How exactly are you starting the listener? Show us the code. |

In the process of extracting the minimal source I actually found the problem in my code. One of my Apps was bound to :443 instead of x.x.x.x:443. Therefore the order of execution played a role here. Issue resolved - my apologies! |

What version of Go are you using (
go version)?1.9.1
Does this issue reproduce with the latest release?
yes
What operating system and processor architecture are you using (
go env)?Windows 2012 Server R2
What did you do?
I have multiple IP addresses assigned to one network adapter: x.x.x.x and y.y.y.y
Golang Web Application is working on port 443 of x.x.x.x
The very same application is copied and configured to work on port 443 of y.y.y.y
What did you expect to see?
TLS on different IP addresses but same ports should not lead to conflicts in ListenAndServeTLS.
What did you see instead?
Despite the fact that the Applications are using different IP addresses the following error will appear when the second application is started:
listen tcp :443: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.
