There's currently no way to know whether an error is for SCTP or UDP, for example: Jul 24 09:55:54.469: INFO: netserver-0[e2e-nettest-3476].container[webserver].log 2020/07/24 09:53:52 Started UDP server 2020/07/24 09:53:52 Error occurred. error:protocol not supported In this case the "Error occurred. error:protocol not supported" is actually for the SCTP socket. Make that more apparent.
