Try the latest version please, if it is still a problem then let me know what error you have in your server logs

resolving for good order, I will still monitor this thread

Thanks and sorry for late reply.

Tested, but the problem still there: https://prntscr.com/f70k95

It will caused all of the sites both front-end and backend 502.

For your information, Here is the way of our buddypress installation, https://codex.buddypress.org/getting-started/installation-in-wordpress-multisite/

we used B of the installation, that might be the reason?

Also, we are using HHVM, Redis cache. thanks.
