Hi @avolinski

Could you precise which target do you use ?

From my side, I got some issue with STM32F7 only.
I have check #4808 and #4809 but there are still some IP connect issue

I believe we're using NUCLEO F429_ZI.

Please note that this fix is not in 5.5.5 Release, should get in 5.5.6 release. If you want to verify with this fix, use mbed-os "latest" which has this fix merged.
