502 Bad Gateway Error

edited November -1 in Bug/Issue Reports

I have been using this hosting for almost a month, it was working fine all this while. Today when I try to access the site, it shows 502 Bad Gateway error (server connection failed and error connecting to the site).

Softaculous Apps Installer also unable to work. It keeps showing the message 'something went wrong, please allow 20 minutes then retry'.

I have submitted a support ticket in cpanel. Please help resolve this issue asap. Thanks.
