Problem to logon on Android devices

[itasp]

found solution in here

Cannot login into Android Rocket.Chat App

I´ve got the same issue than you. I got to solve it adding the intermediate certificate in the /etc/nginx/certificate.crt file (refering the nginx session in the official how to https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/ ) Copy and paste it after the certificate data of the certificate file. The apache approach works because it adds the intermediate certificate in the procedure.

just join certificate with intermediate cert to one file…
