I wonder if there is support for ipv6-only hosts? As you probably can guess I have tried and it didn’t work for me:
Error: NextCloud Error. Status Code: undefined. Message: Error: getaddrinfo ENOTFOUND foo.bar at Object.nextCloudApiRequest (/usr/local/lib/node_modules/n8n/node_modules/n8n-nodes-base/dist/nodes/NextCloud/GenericFunctions.js:39:15) at processTicksAndRejections (internal/process/task_queues.js:97:5)
I’m a bit surprised that whatever library is used by n8n doesn’t support it directly. If anyone can and want to debug this I can provide hostname and credentials for testing.
