Logic apps "message": "BadGateway", "innerError": { "status": 504,

[Donzera]

I am having this issue with my Logic apps workflow. Follow my flow:

I think it is very clear what the flow is doing. On the last step, where it should create the file, I am getting the error below, not sure why this is happening, I could connect without problem to the SFTP, and my IP is whitelisted on their network

"message": "BadGateway",

    "innerError": {

      "status": 504,

      "message": "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond\r\nclientRequestId: 51527505-asdasdasd3",

I am asl receving the same error on the folder path field, which I believe they might be related with each other:

It should show me the folders was created on this server.

Any idea what could be wrong?

Thanks!

Did you equip WAF? Besides, Azure Application Gateway returns 504 Error when the time of the request exceeds 20 seconds

"my IP is whitelisted on their network" - Yes, but the Logic App is running in Azure... you need to add the outbound logic app (app service) IPs...
