Whose page am I supposed to return to?

Whose page am I supposed to return to?
On https://stcommunity.st.com/t5/embedded-software-mcus/how-to-make-ethernet-and-lwip-working-on-stm32/td-p/261456/page/3 I've clicked at : "Actually working STM32 Ethernet and lwIP demonstration firmware".
"Return to my original page" appears to link to https://stcommunity.st.com/t5/embedded-software-mcus/bug-fixes-stm32h7-ethernet/m-p/281420 but clicking onto that does nothing.
