Couldn't enter to environment

[Oleh Sevriukov]

Couldn't enter to an environment when deployment state is Error. Just indicates that it is downloading and that's all.

Step to reproduce:
1. Create Environment
2. Add nodes
3. Start deployment

Expected results:
When deployment has error, you go to Environment in the Fuel UI and get an access to it

Actual result:
When deployment has an error, you go to Environment in the Fuel UI and Environment UI page doesn't open. Just indicates that it is downloading and that's all.

Description of the environment:
1. Fuel 9.0
2. Network Templates with VLAN
3. One node with Virt role
4. One controller in the node with Virt role

Oleh, and what happens when you click the environment block on Environments page to enter into the environment page?
I don't quite understand "Just indicates that it is downloading and that's all." Could you please explain how exactly page indicates that is loaded? Is it possible to make a screenshot of this indication?
Are there any JS errors/exceptions in browser console?

Hi.
This bug was reproduced on environment in scale lab. When I press on any tab in browser, nothing happens, only progress line is going.
In browser i see next errors:

GET https://fuel_ip:8443/api/version?_=1477394340959 401 (Unauthorized)

In Fuel UI value of version parameter is lost (see screenshot in comment #2). For fix this need relogin to fuel, but it is working only for 15-20 minutes.

Thanks Vladyslav,

looks like the issue has the same reason as https://bugs.launchpad.net/fuel/+bug/1616959
and is fixed in 9.1: Fuel version has to be refetched.
