PLC4X

[Nguyen-BangVu]

I am currently working on an application using PLC4X.
The Umati server is running correctly. Everything should be fine

The reason I know this is because everything works fine with UA Expert.
The following log is from the umati server:

all with TCP 8 is from UA Expert and works as expected.
Everthing elsee is an attempt of PLC4X

Both times I used User/Pw identification
I also tried anonymously with the same results

The following log is from PLC4X:

The Error is BadIdentityTokenInvalid
Which I don't understand at all why it pops up

Thanks in advance

I also want to add that it works with the prosys server but not with the umati sample server:
If it helps this is the config of PLC4X:

  "name": "prosys-opcua-connector",
  "config": {
    "sources.prosys.connectionString": "opcua:tcp://10.1.10.106:4840?username=admin&password=admin&security-policy=NONE&message-security=NONE",
