3. What steps have you already taken to try and solve the problem?

I tried many things, including editing the hosts and hostname and no luck.

Tried to verify the CA, the import was ok, I did as the tutorial , one is .pem while the other is .key and imported it via keytool.

I looked into the post of ZrytyADHD from but this one is on a docker and I’m not sure if this problem applies to mine.

I looked into many posts and others places, but it seems none is like mine.

I checked my files, as I looked on others, it’s ok the config, otherwise I wouldn’t be able to open the web page.

I did as is in this page as well How-To Guide: Securing Graylog with TLS

4. How can the community help?

Well, I wish that the community can show me a door so that I can enter and fix this problem so that I can help the community as well, since I’ll be using graylog and I must make this work, and for that, I wish someone could h show me what is wrong.

I thank you all for the help and guidance.

Hi @renoturks,
Could you please provide us full datanode and graylog server logs? I’d need to understand which component is trying to communicate and is failing.

Have you configured TLS for the datanode as well? Uploaded your CA in the preflight interface?

Best regards,
Tomas
