PLC 1152 cannot connect to webpage on LAN

Hello,
I have an 1152 controller, on the ehmi I created a button with an „execute command“ dynamic that is set to open a URL in the same window. The URL is the IP of the Raspberry Pi hosting a webserver on my LAN with a plain HTML page.
If I access the page from another device on my LAN such as my laptop or another raspberry pi HMI, the page loads. So I know the server is working.
When I try and access it from my 1152, I get the „Something went wrong -102“ error.
I’m assuming then there is some kind of security / permissions settings that I might have to change to access pages outside of the eHMI set? What should I be looking for?
Thank you,

I think I know what might be wrong, but do not know how to go about fixing it…
Right now I have two HMI screens accessing the 1152 ehmi page with my button to go to the raspberry pi hosted page.
One screen is a Raspberry Pi HMI as I mentioned in my original post. I was originally using https:// to get to the link which resulted in the „Something went wrong“ error. I realized it was supposed to be http:// as the raspberry pi server is using port 80 and it is not secure (I am not a networking expert as you can obviously tell). So now on this HMI (with chromium browser) I can see that there is a „not secure“ warning in the address bar and then I can change the settings to „allow“ and when I reload the page it now works! Which is great… however…
My second HMI screen is a bwp2102w from Phoenix running the qtbrowser… on this one I have no obvious options to allow the „not secure“ connection. Therefore the screen remains blank and I believe this is the root of my problem on this HMI… The bwp2102w is the actual screen that I plan on deploying in the field and therefore will need to figure out how to automatically allow these http pages to be displayed on qtbrowser
Thank you!

Sorry for the very late answer.
Here is the answer from the HMI support team:

Hello, I did some testing with the hardware 1 BWP. I created a page with a button that Opened a URL form eHMI. The URL is a simple web page on an Ubuntu server. I connected the BWP initially to HTTPS and the simple web page was HTTP

?name=image.pngI found that you have one chance to accept the “Pop-Up”. If you accept, the setting is remembered and you can display the page.
If you don’t accept there is no way that I found to get back and accept, other than reinstalling the firmware.
Unfortunately there are no updates planned for the hardware 1 BWP at this time.
I was not able to duplicate the problem on the hardware 2 BWP.
