Neither Firefox 102.0 on macOS 12.4 not Safari on iPadOS 15.5 can find that site.
And I can’t find a fedoraproject forum on the Fairphone forums — but my eyes might be tired after watching the finish of TdF Stage 4 a few minutes ago — and the Discourse search can’t find it either. Nor can I find any obvious forums on fedoraproject.org
The pukka iPadOS app has no problem locating the fairphone forums.
