It looks like whatever service you are talking to is returning a 504 error, This is likely to be an issue with whatever you are working with and not directly an n8n issue.
To possibly help with this you could try setting the retry option in the node settings so it can retry, If you see this a lot it could be worth raising as an issue with service you are using directly.
Hey Jon, thank you for your help. This error status is already set according to the configuration you mentioned, and this error will still occur.
I also think there is a problem with the gateway, but now I want to know where the timeout of 2.05m is set? Because every time the status is failed, the n8n display is 2.05m.
