can you provide your tb-gayeway.yml? Is remoteConfiguration true or false ?

from thingsboard-gateway.

tb-gateway.log

and here is the tb-gateway.yml

Hi @quirosaur ! Thank you for reporting this issue. I found that the resource files that are provided in the package are not accurate. As a workaround you have to do two things:

1. in opc-onfig.json change "keyPassword": "secret"
2. in opc-onfig.json add "host": <YOUR_HOST>, at the same level as "port" property.

If there are any other issues with the certificate, you can re-generate it as described here
Meanwhile I will update the release archives

Have you solved the problem? @quirosaur

Hi, i tried the solutions, keystore is not apparently problem anymore but opc-ua connection problem persists. here are the logs and config:
opc-config.json.txt
without_opc_tcp_header_tb-gateway.log
with_opc_tcp_header_tb-gateway.log

in "host", should i use ip as "opc.tcp//xxx.xxx.xxx.xxx" or just bare ip?

anyways, i tried both, neither worked.

No, you don't need the "opc.tcp" part, the tb-gateway will add it by itself.
So what happens is that the gateway connects to "opc.tcp://:/", gets the list of endpoints and iterates over them to find the one that matches the security policy.

It looks like that the port 4840 that you are trying to connect to is a local discovery port (by default) in Prosys OPC-UA server, and you have to connect to UA TCP port, which is 53530 by default.
I don't have a working Prosys OPC-UA server, so I was unable to check if the assumption is correct or not

I'm sorry, i accidentally gave wrong name of opc-ua server. It's codesys server.

anyhow, i apparently managed to get connection to opcua. in raspberry pi /etc/CODESYSControl.cfg i added

[CmpOPCUA]
NetworkAdapter=eth0
NetworkPort=4840

this was done in remoteconfig = false, because apparently opcua extension is broken in web GUI.

@mp-loki thank you for help! 👍
