Hi Lukasz,

Actually, I tried that … if you use the opcua:tcp:// version, the error still 
refers to “opc.tcp” … I first thought the same, but when I tried it, I could 
confirm.
Unfortunately, I have no idea how OPC-UA works and I’m not planning on changing 
that any time soon ;-)

Hello Alexis,
Welcome on mailing list, and thank you for interest in PLC4X! Sorry for
delayed answer, you found me (us?) during Easter break.

In terms of URI - the protocol prefix you use is "opc" flavor. Due to
internal library architecture we do not follow OPC specs for connection
string, at least in this part.
Please have a try with "opcua:tcp://...", it should work. Also note that
http transport/xml encoding is unsupported. We cover only binary marshaling.

Kind regards,
Łukasz
