Unknown Transport Protocol

[pauldando]

Hi all,
Having an issue connecting to peers. We have our node up and running, but upon running:
lnp-cli connect 03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f@3.33.236.230:9735
to attempt to connect to ACINQ node or even if we try to connect to one another locally, we receive the following output:
[Unknown transport protocol "03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f@3.33.236.230:9735"](error: Invalid value "03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f@ipv4:9735" for '': Unknown transport protocol "03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f@ipv4:9735")

Please advise.
