Voice command timeout / Unifi Protect - Alexa

After the Nabu Casa Cloud has moved to the new Relayer, the voice commands to my Echo Show ran very, very well! After one of the last updates, I now have a similar problem again, namely that voice commands seem to run into a time-out.

I often use the UniFi Protect integration to look at different cameras. Sometimes the command is accepted after the first time, but then it takes about 10 seconds until the picture appears. Very often, however, nothing happens at all, i.e. you notice that Home Assistant wants to establish a connection but then at some point breaks off.

Does anyone else currently have a similar behavior ?
