Web panel gives 502 bad gateway after install

Impacted versions

• Distribution: Centos
• Codename: Centos 7
• Arch: 64 Bits
• Database: PostgreSQL

problems that occured during installation which i had to fix: (probably not related to this issue, just to point it out)

• Instalator continues even when LetsEncrypt cert is not obtained (got cert manually, SSL now valid and working)
• Nginx config was broken by default (Nginx issue, not your, happened even when i installed nginx before Modoboa - had to add server_names_hash_bucket_size 64; to main config, otherwise nginx wouldnt start

finally after all, nginx is now running, but when trying to access admin panel, i just get 502 error…

From nginx error log:

2018/04/07 19:19:22 [error] 22551#0: *1 upstream prematurely closed connection while reading response header from upstream$

tried some solutions, but i dont know anymore, tried to reinstall too 😢

Same issue here

• Distribution: Ubuntu 16.04.4 x64
• Database: PostgreSQL

I had to run LetsEncrypt manually also. Got it working with nginx

@wUFr Either try a fresh install (on a clean system) or remove the virtualenv before restarting the installer:

rm -r /srv/modoboa/env
rm -r /srv/modoboa/.cache/pip
