Describe the issue/error/question
I have set up a self hosted n8n environment (v. 0.191.1) on my headless raspberry pi in a docker container without any special settings – just a new fresh installation.
When I try to execute a Trello Trigger I get an “Unknown Error”. The GUI does not display any other information. The credentials of Trello are working. When I test the connections, there are not problems.
Since I have it running in a docker container I get some more information out of the console:

I cleared out all possible sensitive information. If any of these information are necessary to give an answer just let me know but the content of the fields made sense.
If I try to create a very simple workflow without a Trello trigger like: Start => Regular Trello Node to create a new Trello card, it works fine. Only the Trigger node doesn’t seem to work at all.
Do you have any hints? Can you tell from these information if the problem is caused by n8n or by my headless-RPi-network-access setup?

I’m pretty new to topics like that.
