IOS 9.3.5 white screen

Hi,
I have an old iPad running iOS 9.3.5 that use to work OK via Safari and that is now giving me a white screen when trying to HTTP on my dashboard. I found a post mentionning something about a bug at some point in time, so I'm wondering if it is possible that the bug resurface? Any body else having this issue?
I'm running the 2.3.4.130 on a REV C-5, and the 2.3.4.128 on a REV C-7 and my iPad displays this white screen when attempting to http on both.
Thanks,
