iOS app won't connect to my plex server



So, inresally like would like to get this one solved so I'm hoping someone can help me. Anyway, I have remote access setup on my plex server. For some reason my wife's iPhone and my iPad will not connect to it. My android bases s8 connects flawlessly and I can stream from it but the iOS devices simply say "connecting" and do nothing. I noticed on my server under devices that I can see it shows the iPad and iPhone as connections but on my server it never loads. Does anyone have any ideas? Surely I can't be the only one with this issue. Thanks!
