Hi @shek, welcome to the community! I am sorry you’re having trouble. Which error are you seeing when clicking “More details” here?

Could it be something like “Unauthorized” suggesting you might simply be using the wrong API Key or is it something else for you?

[shek]

It take a very long time to load. Then when if click “more” , it said :

Couldn’t connect with these settings
ETIMEDOUT

thats all, there is no other error message.

Thanks

Hello @shek

Maybe a stupid question: Is it the same n8n host you want to connect to? If so for what reason? What do you want to achieve?

[MutedJam]

This sounds like it could be a problem with your networking setup (perhaps a firewall somewhere eating traffic). Perhaps you want to try using http://localhost:5678/api/v1 as your base domain so traffic from the n8n node hits your n8n instance directly?

Thanks for responses.

I want to backup my n8n workflow into github.

Thanks it works using localhost one! thanks

[MutedJam]

Amazing, thanks so much for confirming!
