@jwwhite This is an old thread. But I just got my SV3C camera working Monocle to Alexa.

I used rtsp://<ip>:554/stream0 for the URL

Authentication: DIGEST
Audio Codec: None
Tags: @proxy @noaudio

What finally fixed it for me was to login to the camera configuration, set the resolution to 1080P and save the profile and disable the audio

Hope this helps someone. Might work for other generic IP cameras too

Just confirmed this is exactly my issue too. UniFi cams work on echo show 8 but not on echo hub. Thought I was going crazy.

Hi Robert
All working now
Many thanks

@Monocle Robert, You are the man. Thank you so much. That worked.

@mjbarnetto

I have been working on the service backend heavily today; so there were some extended outages yesterday/today.
Please try it again now. You may have to re-link the Monocle Skill to your Alexa account.

Thanks, Robert

@Monocle thanks again Robert.

@Monocle Thank you. Looking good now!

@Monocle Hi Robert, unfortunately it seems to have as it was working for so long i hadn’t changed the settings, I have a Unifi G4 Doorbell, and because the high resolution was higher than 1080, i chose medium resolution at 960x720, when first trying it would not work, so i then had to set the video resolution to 1080 and it would work. I’m really not sure what else it may have been as i hadn’t changed a thing.

Did you have any issue getting unifi-os shell to run. I am not able to get this to run once ssh in.

Hello everyone,
I wanted to share the solution to my DNS resolution issue I encountered with the Monocle Gateway running on my network, which might be helpful for others experiencing similar problems.
Setup:
Cameras: UniFi G3
Controller: UniFi Cloud Key Gen2 Plus
Display Device: Echo Show 8
Router: FRITZ!Box 7590
Issue:
I was facing persistent DNS resolution errors with the Monocle Gateway service, which prevented my Echo Show from accessing the camera stream. The error message indicated a DNS resolve error for the Monocle DNS address.
Solution:
The issue was related to DNS-Rebinding protection on my FRITZ!Box 7590. Here is how I resolved it:
Access the FRITZ!Box Interface:
Open a web browser and go to http://fritz.box.
Log in with your FRITZ!Box credentials.
Configure DNS-Rebind Exceptions:
Navigate to “Home Network” > “Network” > “Network Settings”.
In the “DNS-Rebind-Schutz” section, add the problematic DNS hostname to the exceptions list.
Click “Apply” to save the changes.
Restart the FRITZ!Box:
Go to “System” > “Backup” > “Restart” and click “Restart”.
After making these changes, the DNS resolution issue was resolved, and the Monocle Gateway service started working correctly with my Echo Show.
I hope this helps anyone facing similar issues.
