This happened to me one time. Said the certificate or something wasn’t valid. And I couldn’t go on brotherhood at all. Was so weird. It happened after I cleared everything and closed everything on my phone because I had so much shit open. Then next day I went to get on and it was ok. I browsed to see if I read anything about it. And saw nothing. So felt like maybe it was a glitch from my phone. But it happened to u now. Maybe someone trying to hack the shit. With all these hackers lately. Idk. But I’ve dealt with it. Atleast u could go on the page. It wouldn’t let me at all go on.
