Can't fix “cannot verify server identity” error
My two iphones (iphone 7 and iphone 11) suddenly have this issue at the same time. I looked up online for solutions but none can fix mine as other people's server issue is related to gmail or imap, but mine shows the identity of "server4.websitehostserver.net" cannot be verified. For more details, it shows the certificate is *.greengeeks.net issued by AlphaSSL CA - SHA256 -G2 with "Not Trusted" in red. I don't recall I download any new app or I have any app named that. Please see more details below. I guess we need to figure out which app or setting cause this, otherwise we can't fix it. It's been annoying for weeks. Really appreciate if anyone can help.
