Trial license 502 Bad Gateway error

[ZbyszekL]

Hi,

I did a fresh install of PLESK 12.5.30 on Debian 8.

I tried to put a trial license key i license manager but every time I got 502 Bad Gateway NGINX error.

So far I tried solutions:

ls -lta /etc/sw/keys/registry.xml
-rw-rw---- 1 psaadm swkey-data 923 sty 31 09:32 /etc/sw/keys/registry.xml

On my test server I see:

[root@ppu12-5 ~]# ls -lta /etc/sw/keys/registry.xml
-rw-rw---- 1 root swkey-data 1596 Feb 1 05:28 /etc/sw/keys/registry.xml

In this article https://kb.odin.com/en/126289 point 2:

Make sure the file '/etc/sw/keys/registry.xml' exists and and has correct permissions:

# ll -lta /etc/sw/keys/registry.xml
-rw-rw---- 1 root swkey-data 9908 Aug 22 10:54 /etc/sw/keys/registry.xml
