Unity Hub Sign In Window - Blank.

I installed Unity Hub and clicked sign in and a new window popped up that is just blank. I tried waiting and running as administrator. I've tried reinstalling it but same deal.

8GB DDR3 RAM - EVGA GTX 1080 8GB - Windows 10 Pro x64 - Gigabyte Mobo



what happens if you close the window with the 'X' in the top right corner?

It just closes that window. When I click to sign in again it displays a blank window again.

[edit] I just updated my graphics card drivers and same deal. Rebooted the PC and it does the same thing again.


That window is populated from a web view. Do you have a firewall set up? You should ensure that it allows the hub to connect to the net.

Same here.

First, the "Loading..." page hangs for 60 seconds.

Then "Welcome..." page appears with the login button that opens a completely blank window.

I was thinking I could specify the license file manually but the link "deploy a license file" does nothing.

Windows 10 Pro x64. No special firewall rules, MS Edge and IE 11 (both x86 and x64) work fine.


If I launch Unity Hub for the first time, nothing visually happens, no windows at all, but I see two "Unity Hub.exe" processes running.

If I launch Unity Hub for the second time, I get three processes running and this time see the window: 60 seconds of the "Loading" page and then the "Welcome" page that doesn't work.

If I close all the windows, the third "Unity Hub.exe" process goes away but the previous two continue running until I kill them manually.

@Amon_1 and @alexzzzz are you able to reach https://id.unity.com guys ?

I can send you Process Monitor logs if you like.

@alexzzzz Unfortunately, I don't think Process Monitor logs gonna be a great help here.

Could you please do the following:
1 - Closes all Hub processes (ensure nothing left in the Task Manager)
2 - Start an editor (through the Unity.exe)
3 - You gonna land on the "old" launcher, from there, try to sign in an let me know if you face the same issue

Thanks a lot for you collaboration!

I have 4 installations:

2017.1.3f1, 2017.2.1p1, 2017.3.0p1 -- these three asked me to login.
2018.1.0b4 --- this one opened the list of my projects.

I checked all the installations first and then successfully logged in using 2017.3.0p1. No problems, everything looks normal.

Let me get someone from the sign-in team to see if they can find the problem

It works!


Same problem here:

  • Install Hub and launch it
  • First window invites me to login or create an id. I click to login
  • New window opens but is blank and remains blank.
  • I close the blank login window using the X, click again to login, same thing.
  • I close the hub, run it again, no window shows up at all.
  • I look in the task manager and see two Unity Hub processes.
  • I kill the one with more memory allocated (~80MB) and both vanish.
  • I run the hub again but no window shows up at all. 2 Unity Hub processes in Task Manager, rinse and repeat.
  • I open Unity 2017.3, it logs in automatically just fine.
  • I close Unity 2017.3, open hub, no window shows up at all.

I haven't rebooted yet.

Yesterday my Windows (Insider Preview) decided to update and I agreed. After the update the issue with the hub had gone. I thought it was a coincidence and the guys did actually fix something.

Computer freshly rebooted, same behaviour: I launch the Hub but no window shows up, just two processes in the Task Mananger, one taking 75MB the other 35MB.

I uninstalled and reinstalled the Hub, and noticed that after installation it auto-launches itself. But just as described, the window doesn't show up, just the two processes. Whehn I installed it originally, it did seem to run automatically, but I assume it ran the two ghost processes just like now.

So I launched it again without killing the existing Hub processes, and the window appears (along with a 3rd process now). Same behaviour as the first post, blank login window.

If I kill everything and launch the Hub twice then the Hub window shows up consistently. But the login window will still be blank.

(Windows 10 64-bit fully updated, Hub 0.11.0)

I am facing similar issues with unity Hub. Canot login to my account.
And it also cannot download the Learn section "01 : Play & Edit Mode " tutorials or any of the tutorials.

yep same 2 issues: Both on hub AND unity when it was fine yesterday.

Several minutes later, it finally loads the main screen -- however, signing in results in indefinite white screen

I have a feeling it may have to do with init loading -- there's no way the first loading should take that long. I think it actually timed out BEFORE getting to that screen. However, internet works fine -- I can sign in fine within Unity. That ID link posted above works fine for me. Using default Windows 10 firewall.

Something else I noticed: Checking license if I open directly is going a bit crazy and is also indefinitely staying here:

Every 1/2 second, the center text flickers. Every now and then, I'll see the top bar appear and load to 100% in only 1 second. Then poof. It seems like it's pinging every 1/2 second and failing (which is in my head when you said firewall). However, I've authed fine for the past few years: It's only when I started using Hub and 2018 (originally 5.6). Even then -- I signed in fine earlier. I really don't know what's causing it, but it seems server-side.

I'm stuck! I can't get in anywhere.

To add, the license check is also super jumpy ^

This issue seems intermittent: I found a workaround (not a solution) to manually activate by disabling the internet. I'll then be prompted to a URL to copy+paste something, download a file, then upload it back to Unity -- then enter my serial again. I then turned on my internet again. After this, both hub and Unity started working again.

Who knows how long until it starts doing this again. I found an FAQ about this that was useless -- turn off antivirus (first thing I tried), ensure firewall isn't blocking 80 or 443 (that's literally http and https/ssl/tls -- no one blocks those or they wouldn't even be able to download Unity or even post here -- or anywhere, for that matter, haha). Then an unstable connection (I'm on a cat6 wired 450mbps connection using Google DNS - no way).

This is absolutely a Unity issue. If it wasn't, I wouldn't be able to sign in just fine after manually activating (especially since a mod above confirmed the same id url is the access point for all the related sign-ons).

Same here except I can clic on my project in Unity Hub, it's loaded and then a white screen stays there:
