This ended up being a CSP issue, effecting all ios browsers (because webkit) and safari in osx. Unfortunately this has led to a blank screen for safari for this whole time. 
Fixed now (pending a merge to prod), works in safari/osx and ios: https://gitlab.com/librespacefoundation/satnogs/satnogs-network/commit/3c5d5105a6b7caae7730d7dbd347b0ded7f26bdc
