I got this last night, and though I maybe put the url wrong or the url changed (since kumos is in building process it's not weird to get some outdated links)
Error
We encountered an error when trying to load your application and your page could not be served. Check the logs for your application in the App Platform dashboard.
But now I'm sure the url was right since it loaded right five minutes ago Poor Mauve isnt getting the scissors he asked me for soon :B
Anyway, please have a check on this?
Note: it's going on and going off, it's not a permannet error.
