Self signed certificate issue in certificate chain in MongoDB cluster

Hi Team,
I am new to mongoDb atlas platform. I have a problem while I am connecting cluster db from vpn/wvd…anyone can help me…thanks in advance…

Okay, we’ve learned you have a problem, and that it has to do with certificates.
Can you describe the problem a little more fully, please?

Sorry for the delay reply.
I can connect to my cluster without vpn, but the same cluster I can’t access from WVD showing error as Self Signed Certificate issue in certificate chain. I am not using any certificates to connect the cluster through WVD

Who manages your VPN?

Server Administration Team. Firewall team unblocked 27017 port still we are getting self signed certificate issue

What is the environment from which you connect successfully without a certificate error?

its my local system (laptop without connected to VPN). certificate issue arises from while connecting through WVD

So you are in Azure?

Free cluster account created through aws and accessing that account through locally installed compass

You may have to talk to AWS support or read more documentation about setting up a VPN. The error isn’t MongoDB, it’s something in your environment.

Yah, its Windows virtual Desktop, from that environment getting issue. When local system connected to Global VPN also same problem arises

But you say there is no certificate installed with your MongoDB installation, self-signed or otherwise?

yah no certificate I installed during the creation of mongodb cluster

no certificate we are used while creating cluster account. And if we tried with allow access anywhere for testing purpose, at that time also WVD not connecting

Sounds like your VPN is problematic.

can you please suggest any solution we need to look around. That will help the network team to look on. What about your suggestions to overcome this issue?

Read the MongoDB FAQ: Security and make sure your VPN and operating system accept the Let’s Encrypt’s root Certificate Authority (ISRG Root X1)

Thank you for the update, Jack. I have a concern: can we directly use the ISRG ROOT X1 certificate, or do we need to generate a self-signed certificate for WVD? Will it solve our problem? We are currently stuck in our project. Could you provide a certificate for WVD testing purposes?

If I correctly understand your problem, @shyama_lakshmi , some part of your setup is not accepting MongoDB’s Let’s Encrypt certificate. I do not know where it is not being accepted … in your VPN security software? In WVD? I cannot tell from your description.

You should try first downloading the ISRC Root and install it in WVD and see if that works.

I tried with the mentioned certificate, downloaded and saved as .pem file. I am trying to connect my cluster from WVD platform and uploaded the .pem file via compass, same certificate issue message is showing. FYI: Attached Screenshot
