@karsten13 good option. I tried it (actually I placed the option directly in the electron.js script) but it doesn’t change the situation at all.

@stephanvdplas There is another thing:

In the preview tab of the content it shows: Failed to load response data: Connection is closed, can’t dispatch pending call to Network.getResponseBody

@sdetweil said in iFrame blank when displaing http://<ipaddress LMS server>:9000/material:

@stephanvdplas said in iFrame blank when displaing http://<ipaddress LMS server>:9000/material:

Set-Cookie header didn’t specify a “SameSite” attribute and was defaulted to “SameSite=Lax”

Ok, I don’t KNOW for certain, but our cors proxy might work there

change the url in the iframe config to

http://localhost:MM_PORT/cors?

the rest like this

// the url 
url=http://www.test.com/path?param1=value1 // example
// if there are headers, skip if not 
&sendheaders=header1:value1,header2:value2&expectedheaders=header1,header2

make sure quotes around the url string’’

It doesn’t work. Now there are no errors, but it only shows an empty frame.

In the Preview tab, it shows {{snackbar.msg}}
[24-09-18 22:33:38.8839] Slim::Utils::Misc::msg (1319) Warniing : [22:33:38.8838] “my” variable $mobile masks earlier declaration in same scope at (eval 5777) line 46.

This warning is also seen in the debug log of LMS server, also when I open the 192.168.3.8/material on a browser on a windows machine (where the site is loading correctly).

@stephanvdplas in the network tab I see errors:

This Set-Cookie header didn’t specify a “SameSite” attribute and was defaulted to “SameSite=Lax”, and was blocked because it came from a cross-site response which was not the response to a top-level navigation. The Set-Cookie had to have been set with “SameSite=None to enable cross-site usage.”

@stephanvdplas no errors at all! Only a deprecation warning but it is about a different module .

Please help me to further troubleshoot. All other web content I tried is working fine and the content I want to show is working fine when browsing the mirror in a different browser via http://<ip address mirror>:8080.

So it must be some strange thing in electron or jsnode.

@sdetweil ok I’ll have to attach a kb and mouse to the pi then. Will try this tonight.

O, to add this probably important information: This issue only exists on the mirror (Rpi Electron app) itself, not when browsing from another device to http://<ip address mirror>:8080. In that case it works perfectly well.

I have used the iFrame (as well as MMM-iFrame) module(s) for showing the material skin interface of the Lyrion Media Server, formerly know as SqueezeServer or Logitech Media Server.
But since the latest MMM update (2.28.0), the iFrame show completely blank.
There are no (mpm) log errors or warnings when restarting MM2. Other websites, e.g. nu.nl as well as http://<ipaddress LMS server>:9000 (so the standard skin) are working.
How can I troubleshoot this?

Hi @bdeelman ,

I have used this 80-20 mirroring glass:
