Problems with MyOpenHAB Cloud

EDIT:

Possibly the easiest to explain in short. I also see this problem when opening this link in a Browser.
home.myopenhab.org/rest/items/HMLCSw2PBUFMPEQ0639547WohnzimmerOben_2_STATE
On first try I need to give Username and Password. Then I get the expected result. On a reload of that page after e.g. 10 Seconds, I get a blank page with Content Length 0. When i wait over a Minute and reload, I again get the expected result. Shorter reloads always result in Blank pages.

What additional Information can I provide?
How can I fix the Problem?

EDIT END

I have several Problems they are possibly all related to MyOpenHAB.

  1. Openhab Cloud:
    https://home.myopenhab.org/overview shows most of the time just an empty Page and has different Errors in the Developer Console. Most of the time something like the manifest.json has a length of 0 or the https://home.myopenhab.org/res/icons/144x144.png has a length of 0. Or similiar.
    A test with curl works on the first call, but returns 0 length on a second call. Waiting some time, the first call works again but any subsequent call will result in 0 length.

Locally the command works without problems.

curl -b cookies.txt -X GET https://home.myopenhab.org/rest/items/HMLCSw2PBUFMPEQ0639547WohnzimmerOben_2_STATE -v -u user:pass

  1. Alexa:
    When switching Items with Alexa, the Items switch, but Alexa is complaining the Device is not responding. Also in the Alexa App all Devices show a red exclamation mark. In the App Devices can most of the time just be turned on because Alexa most of the time can’t read their status and only sends an On Command but most of the time does not receive the update.

  2. Google:
    Also all off the Devices seem Offline and not responding.

I tried to reconfigure Openhab Cloud multiple Times and re authenticated the Alexa Skill multiple times.

What else can I try?
