Problem sending command

I successfully connected my Dragino LT-22222-L from TTS CE (TTN V3) to myDevices using the webHook. The data from the LT-22222-L are received and displayed.
When I try to transmit a value e.g. to switch on an output, I get the error-message “Problem sending command: unable to get local issuer certificate”.
What am I doing wrong or where can I find this certificate ?

can you share a screenshot of the error you are getting.

Thank you for your answer. Here the screenshot with the error-message:
I tried to actuate relay 1.

I have same problem!

@wolfpcgn do you found solution?

No, until today I found no solution. Everything is working fine when using the TTS CE (TTN V3)-console, using Cayenne I still get the same error-message.

If someone could help with this problem I would be very thankfull too.

we are looking into the issue. will let you know when it is fixed.
