New docker install, nginx 502 error

I’ve been trying for a while now, and I cannot get Seafile to work. I’ve followed the docs and copied the given docker-compose just changing passwords, hostnames, etc. as the docs say to do, and I’m consistently getting a 502 error. I can’t figure it out. I haven’t changed anything. I’ve tried installing on multiple systems. But still, 502 error. I tried different versions of Seafile as well going back a few months.

Any idea on how to fix it? I would really like it work

The issue might be memcached. I tried it with an older version, and now it’s functioning. I’m not entirely certain that that’s the problem, but it seemed to fix it.
