I have joomla 3.x installation along with few custom component and modules. admin part is working very well but on front side I receive 502 bad gateway error. I check the error log and found the error message given below.
upstream sent invalid header while reading response header from upstream, client: 127.0.0.1, server: hospital, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000"
Appreciate if anybody can help or provide a clue to solve it.
Thank you.
