Problem with registering atlassian-connect-express addon

Hello! Since today morning i’m experiencing problems with registering my atlassian-connect-express addon on my JIRA Cloud server. Yesterday everything was fine. Neither hello-world example or my addon works. I’m installing addon through
endpoint, but it responds with 401. The credentials are 100% fine. The strange thing is that on other jira cloud servers it’s totally installable. Our jira host contains hypen (, maybe this causes the problem? Cause i’m also getting the error “Add-on not registered; no compatible hosts detected”

EDIT Strange things are. Everything working just fine now. Close the topic please.
