Problem to access Upgrade page

[furuzi]

Dear all,

I have a fusionpbx 4.2 work fine all but I have problem to access to Upgrade page (advance/upgrade) when I try to open page have an error: 502 Bad Gateway.
I try to disable fail2ban and firewall without success.
Have you an idea how can I fix the problem?
Than you.

Have you restarted nginx or rebooted your server? I'd probably start there.

Yes I have alredy rebooted server and restarted nginx but not work. It seems like a permissions problem but they are the same for all files and folders.
