Mainsail won't load on web browser after installing Klipper Screen

Hi, I have a Voron 2.4 and it was working fine before installing Klipper Screen but now, Mainsail won’t load on the web browser.
Some context. I have a Voron 2.4 in my university and I was trying to install Klipper Screen but it wouldn’t let me clone the Github repository to the Raspberry Pi due to wifi/DNS isssues. I took the SD card out of the printer and took it home to install Klipper Screen from my Raspberry Pi and it worked so I took it back and put it back in the printer. Klipper Screen works fine since the printer follows whatever command the touchscreen does. Not sure what the problem could be but any help is appreciated.

I think the error might be relayed to network manager since I get this error when booting up

Not sure if this will work for you, but for me I had to log back into wifi on the screen then it worked.
