problem with Remote Node on v1.15.0

[kamandir]

hey there!

Thanks for the new nice stuff released! I started some testing and found challenges...
maybe it's me doing something wrong, but i will still report it to find out why it fails... ;)

whatever i do, all the time i hit this error (code 500) when try to change from local node to a remote.
Config:

# Remote DAGU Nodes
remoteNodes:
 - name: "DEV" # Name of the remote node
   apiBaseUrl: "https://_my_dev_node_.com:8443/api/v1"
   isAuthToken: true
   authToken: "bla-bla...."

Error:

GET https://_my_dev_node_.com:8443/api/v1/dags?page=1&limit=50&searchName=&searchTag=&remoteNode=DEV 500 (Internal Server Error)

@kamandir Thanks for reporting the issue! I’ve been trying to reproduce it, but everything seems to work fine in my environment. Here’s my setup:

1. Running server 1 on port 8080 and server 2 on port 8081.
2. Server 2 is configured with IS_AUTHTOKEN=true AUTHTOKEN=123456
3. The admin.yaml configuration is as follows:

# admin.yaml
port: 8080
remoteNodes:
  - name: "dev"
    apiBaseUrl: "http://localhost:8081/api/v1"
    isAuthToken: true
    authToken: 123456

4. API requests with cURL

curl --location 'http://localhost:8080/api/v1/dags?remoteNode=dev'

With this setup, both the API and WebUI on localhost:8080 are working as expected for me.

Could you share a bit more about your setup so I can dig into this further and try to replicate the issue? Thanks! :)

[kamandir]

i'm running it on a secure port with a certificate installed. Does this make difference?..

PS: I have a side process that utilizes the API and all is fine there, API calls work with no issues.

[yohamta]

Thanks for the information! I'll try to fix.

@kamandir Thanks for reporting the issue! I've released v1.15.1 that should fix the HTTPS connection problems.

You can now configure TLS verification skipping per remote node like this:

remoteNodes:
 - name: "DEV"
   apiBaseUrl: "https://_my_dev_node_.com:8443/api/v1"
   isAuthToken: true
   authToken: "bla-bla...."
   skipTLSVerify: true  # Add this line if you need to skip TLS verification

Please try it out and let me know if you're still experiencing any issues. Thanks for helping improve Dagu! 🙂

@kamandir, thank you for testing! Could you please share the server's response body from the network tab in your browser? It should include an error message.

[kamandir]

sure:

{
    "detailedMessage": null,
    "message": "failed to send request to remote node: Get \"https://_my_addr_.com:8443/api/v1/dags?limit=100\": tls: failed to verify certificate: x509: certificate signed by unknown authority"
}

some snippets from my browser to ensure the cert is fine:

[yohamta]

@kamandir Thanks! It looks like a certification issue. Have you tried with skipTLSVerify: true in the remoteNodes setting?

[kamandir]

cool it helped. with the "skipTLSVerify: true" I see no error anymore. Thanks!
But I'm sure my cert is OK ;)

[yohamta]

I'm glad to hear the workaround worked! I'll look into why the certificate didn't function properly later.
