Unable to register webhook

[Elektroniker]

Hello,

when trying to register a webhook, the message comes that there is already a webhook registered. Although the App was completely freshly created and only the environments were created.

Then when I try to query the mentioned webhooks via API, but comes that none were found?!

E, [2021-11-20T09:52:41.346987 #11252-193300] ERROR -- : Unable to register webhook: Unable to connect during CRC GET request. Already 1 webhooks registered. Maybe you need to delete one first.

Creation and query are in the same app, with the same environments (freshly created).

Thank you in advance.
