Can add package manually. can access download.packages.unity.com,but can`t ping

 

unity 2018.3.0f2
unity hub 1.4

2018.2 has the same problem

 

Yes，im in China。
2018.2 and 2018.3 can both load packages this morning,
But 2018.3 start loading again at 3 hours later.
2018.2 keep loading too when 2018.3 is running.But 2018.2 can load packages solo.
Vpn didn`t fix this problem.

 

Hello @MonsterYu,

Please try something for me:

• Start Unity offline (completely disconnected, no wifi).
• Are you able to start the Editor?

There are some issues with our availability in China.
VPN will not solve this issue, unfortunately.

Cheers,

I am getting the same message when I try to search for anything. I am trying to search for Windows Mixed Reality because I am trying the solution to the issue in this post :
https://forum.unity.com/threads/can...-perceptionremoteplugin-dll-not-found.514935/

I am sometimes connected to an organizations private wifi. Could it be a firewall setting?

 

Cannot perform upm operation: getaddrinfo EAI_AGAIN packages.unity.com:443 [NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

Error searching packages online.
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

 

That fixed it. Thank you

 

This solves the issue for me only for packman looking for updates (when opened). When switching the platform of my project, there happens a packman request somehow which fails now:

Operation UnityEditor.PackageManager.Requests.SearchRequest failed with Error: UnityEditor.PackageManager.Error
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

Edit: after setting the proxy settings, the asset store is also not available out of Unity anymore.

 

PackageVersionLookUpdata.Update: Package Search Request failed
how to fixed it?\

 

I'd checked the pinned thread around troubleshooting common problems

 

Hi I went to help > manage licence and reinstall my free licence

 

a simple sign out and sign in fixed mine.

 

You are my hero!
