Since about one hour ago (Monday, 22 August 2022 CEST 15:00) the nitro.chat matrix server is not available any more in neither of the clients I tested. The Webinterface at [https://app.nitro.chat/#/login](https://app.nitro.chat/#/login) throws the following error: “There was a problem communicating with the homeserver, please try again later.” [https://nitro.chat/\_matrix/client/versions](https://nitro.chat/_matrix/client/versions) displays: “502 Bad Gateway” What is the problem and when will it be fixed? ---

It was a planned maintenance and it’s working again now. ---

Thanks for the fast reply. I can confirm that it has been working since. Where do I see the schedule for planned maintenance?
