Behaviour of the extension on an exotic port

[9Marin]

Hello,

I am submitting this issue because as part of my work I am working on a web application exposed on port 9393.
The requests I send via the repeater or the proxy are not replayed by the extension.
I then checked on an application on port 443 and my extension works without a problem.
Is there a parameter I've missed that allows this type of request to be replayed?

With kind regards,
