Recently I’ve noticed that whenever I attempt to go to the Azure portal (portal.azure.com), that I receive a blank page/screen back!
Azure Portal – Blank Page
Notice that the URL shows as: https://portal.azure.com/signin/index/?cdnIndex=2&l=en.en-us
The “l=en.en-us” part obviously means the language is English. But even if we remove that part, still nothing loads.
Then we have the “cdnIndex=2” part. I’m not sure what the “cdn” stands for (either “Content Delivery Network” or “Canadian”, since I’m in Canada). But if we change the index from 2 to 1 (“cdnIndex=1“), we get the login screen. At least we’re making progress!
Azure Portal – Login Prompt
So that’s good… but, it’s not what I’m looking for. Since I’m logged into my @outlook.com account (which my subscription is linked to), I’d expect single-sign-on (SSO) or “pass-through” to log me in directly.
My “solution”, because it really isn’t one, is to remove the “?cdnIndex=2&l=en.en-us” portion of the URL, which results in this: https://portal.azure.com/signin/index/.
When I do that, I can see the pass-through authentication working, and the URL changes to “https://portal.azure.com/?pageVersion=5.0.302.3979276.160616-1104” momentarily, before continuing.
Azure Portal – Login Redirect
Eventually I am logged into the portal as expected.
Azure Portal – Logged In
So, I don’t know why this is occurring, if it is because I am accessing it from Canada (since the new Canadian datacenters are online now), or what.
But if anyone has any other input, etc. please contact me and I’ll amend this article.
Any ideas at all as to why this may be happening?
Everything was fine for me Friday evening, however, this morning I experienced the very same thing.
Hey Jeff, I do not know why it’s happening. For me it’s been happening for a few weeks now. If you do find a solution or any other details, please contact me and I’ll add those notes to this post. Thanks.
