Mailinabox V68 when connecting with /mail or /cloud receiving 502 Bad Gateway and Android clients force to verify email address again.

Mailinabox V68 when connecting with the /mail or /cloud I am receiving 502 Bad Gateway. The Android email clients are not updating emails on the devices. I looked at the /var/log/nginx/error.log and it contains a lot of these errors messages.

When I reboot the email server the clients both Android Phone and Webmail connect for a short period of time. Then I get the 502 Bad Gateway for the Webmail clients and the Android Clients are prompted to verify email address (sign in again).
