Can't register toon channel

What does your question relate to:

Channel(s): ______
The Olisto app
toon channel
Other

Please add the correct tags [app-improvement, other or “channel-name”]

This functionality has not been asked before:

I have checked the Olisto FAQ
I have searched the forum and I can’t find a similar topic. (If you did, reply to that topic instead of making a new one)

What version of the app do you have?

You can check in the app this under ‘More --> Profile --> Settings’

2.25.4

Which device and operating system do you have?

e.g. Samsung Galaxy S10, Android 9 or iPhone Xr iOS 13
OnePlus 3

Can you briefly describe what happened and what you expected to happen?

(Add any screenshots/photos where useful)
Adding the room trigger asks me to log in. After logging in the webpage shows;

{"fault":{"faultstring":"Execution of ServiceCallout SC-eneco-login failed. Reason: ResponseCode 500 is treated as error","detail":{"errorcode":"steps.servicecallout.ExecutionFailed"}}}

Was it a one-time event or reproducible?

One-time event
Reproducible by registering toon as a new channel

What did you already try to fix the problem?

Restarting the app, reconnecting the channel

Same problem here. Toon hardware not visible in Olisto or Google home app

I fixed this by logging in using my Eneco credentials instead of my toon credentials

We are aware of the problem and are working on solutions. For some it may work again already, for some it may not. We will keep you posted on further development.
