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: ![UPM Error][1] Also the Unity Package Manager keeps showing this log: Path: C:\Users\gama\AppData\Local\Unity\Editor\upm.log Log File Link: https://drive.google.com/file/d/13kShPGDMauT7Dimztr9S4BUxQru5yeUv/view?usp=sharing I can open the Nexus repository page on Chrome, which shows my new certificate correctly, but Unity seems not loading this new certificate. ![Valid Certificate][2] 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. [1]: /storage/temp/160992-upm-certificate-expired.png [2]: /storage/temp/160993-nexus-repository-certificate.png
