Unity Package Manager - Certificate has expired

Hi there,

My project uses some plugins from a Nexus repository, as can be seen on this manifest.json from Unity Package Manager:

UPM Manifest Link:

https://drive.google.com/file/d/1nWbosR2YnrMy1dOjvdnFPYE85RgvuPpE/view?usp=sharing

I’ve updated my Nexus server certificate, which the following error is showing up when opening my projetct:
160992-upm-certificate-expired.png

Also the Unity Package Manager keeps showing this log:

Path: C:\Users\gama\AppData\Local\Unity\Editor\upm.log

Log File Link:

I can open the Nexus repository page on Chrome, which shows my new certificate correctly, but Unity seems not loading this new certificate.

Can someone help me?

I’ve reimport the entire project, deleted the project, uninstalled all Unity versions, deleted all residual Unity folder and files, cleared all entries on Windows Registry, restarted the pc, but after it the same error persists.

My Environment:

Windows 10

Unity 2018.4.21f1 - Pro

Thanks in advance,
Carlos Gama.

Same problem with Unity 2019.2.19f1.

I have used https and http - same error.
