Why do we see SSL_ERROR_SYSCALL on outbound timeout?

[Fantaztig]

Hi!

We are sitting behind a corporate firewall that will just let connections that are not allowed time out.
This causes some issues when our customers try to connect to services not allowed in the firewall because linkerd gives them a SSL_ERROR_SYSCALL (in curl) or some other seemingly SSL related error on their side when linkerd's outbound connection timeout hits.
Is there a way to configure linkerd so that outbound connection timeouts will actually show as e.g. a gateway timeout to the client?

The real problem here is that the error doesn't really hint at the problem (timeout/no firewall clearance) and people spent their time on debugging whether e.g. root CAs are present in their pods etc.

Cheers!
