Nitro.chat matrix server is unreachable

Since at least 45 minutes ago (Monday, 08 September 2022 CEST 16:00) the nitro.chat matrix server is not available any more.

The Webinterface at 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 displays:
“{“versions”:[“r0.0.1”,“r0.1.0”,“r0.2.0”,“r0.3.0”,“r0.4.0”,“r0.5.0”,“r0.6.0”,“r0.6.1”,“v1.1”,“v1.2”],“unstable_features”:{“org.matrix.label_based_filtering”:true,“org.matrix.e2e_cross_signing”:true,“org.matrix.msc2432”:true,“uk.half-shot.msc2666.mutual_rooms”:true,“io.element.e2ee_forced.public”:false,“io.element.e2ee_forced.private”:true,“io.element.e2ee_forced.trusted_private”:true,“org.matrix.msc3026.busy_presence”:false,“org.matrix.msc2285.stable”:true,“org.matrix.msc2285”:false,“org.matrix.msc3827.stable”:true,“org.matrix.msc2716”:false,“org.matrix.msc3030”:false,“org.matrix.msc3440.stable”:true,“fi.mau.msc2815”:false}}”

When will this be fixed?

This was an unplanned server downtime. NitroChat is up again now.

What do you think about xmpp vs matrix?
