Traefik n8n workflow could not connect self hosted Baserow

Traefik Traefik v2 (latest)
1

I have deployed n8n and Baserow in a Digital ocean droplet. I have used baserow.mydomain.com and n8n.mydomain.com subdomains for Baserow and n8n serverices respectively. Traefik has used as a proxy in front of containers. Both services can be accessible using their subdomains. However, when I tried to connect Baserow node from n8n workflow,did not work. My N8n, Baserow and Traefik configuration are given bellow-
Traefik/docker-compose.yml :-

I can access to n8n application using https://n8n.mydomain.com/ and to Baserow using https://baserow.mydomain.com/. However when tried to connect from n8n workflow to a Baserow node using following URL and Credentials the Baserow rows were not loaded
API URL : https://baserow.mydomain.com/
UserName: baserow
Password: password.
On the other hand I can fetch the API successfully using Postman or any RESTclient. TIA

Go into your n8n container (docker exec) and try a ping and curl/wget with baserow domain, to see if it works (DNS IP resolution, network connectivity).

If you don’t mind an internal connection (bypassing Traefik), you could use their service names to connect to each other (from Docker DNS, like http://baserow), because both are connected to the same Docker network.

Thanks for reponse. Ping from n8n container to baserow domain is working. Hower, insternal connection not working http://baserow.
