Opening a workspace doesn't work. It is stuck in "Loading a runtime token...".
Workspace should open, I assume I should see some kind of code editor.
kubectl version) oc version)minikube version and kubectl version)minishift version and oc version)docker version and kubectl version)

Exactly the same problem here
I use Google Chrome.
Same problem, but fixed when reset the experimental features.
If it's the same situation, try it.
chrome://flags/ -> "Reset all to default"
And "*.openshiftapps.com" cookie blocked?
Try allow it.
Please also double check that your adblockers/privacy extensions aren't blocking connections -- since workspace routes have semi-randomly generated names, it can trigger some heuristics.
yeah, please take a look at FAQ - https://github.com/redhat-developer/rh-che/blob/master/FAQ.adoc#can-not-login-to-che-openshift-io-authorization-token-is-missed
I use Firefox and I block 3rd party cookies. After allowing cookies from openshiftapps.com the workspace is now loading.
There should be some kind of error message indicating what the problem is.
Just showing a progressbar forever is poor user experience.
BTW, the FAQ does not mention anything about openshiftapps.com
I had the same issue using Chrome. It would be helpful to have the FAQ updated when the requirements change. I added the following to my Settings for Cookies and Site Data in Chrome and it worked.

Workspace loader failed to do something, right? Then it must clearly say it and in addition, give a hint that it might be blocked cookies issue.
However, the loader did not fail outright. It got stuck in a loop. Perhaps it can perform a pre-check, or we can clarify the documentation.
I've just tried opening a workspace on che.openshift.io and I get the Loading a runtime token loop as well.
In the console I've found:
Access to XMLHttpRequest at 'https://routectlqpqce-jpinkney-12-che.8a09.starter-us-east-2.openshiftapps.com/jwt/auth' from origin 'https://che.openshift.io' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
@JPinkney It's another issue. jwtproxy for your workspace seems to be unavailable. Pleasem register a new issue and put devfile there.
This is still happening on: Chromium to 85.0.4183.121.
It's repeat-looping through the authentication cycle, flashing the "Loading a runtime token..." message.
@Wisedemic: I'm no longer experiencing the problem after making the adjustment shown in my comment above. However, it would be nice to know this up front as opposed to having to discover it via Google searches. I suppose most developers just accept third party cookies by default.
Keeping these 3rd party cookies will only turn potential users away from che because it "doesn't work" from their point of view.
