I install magento 2.1.0 with varnish and nginx.
All works fine until I active full page cache.
When i enable it, all work fine except some category
Top category did'nt work and return :
Error 503 Backend fetch failed
All other pages work fine. So I suppose this is my issue :
I put a huge value on http_resp_hdr_len and restart my varnish but nothing change i always got this issue.
I varnish log i can read :
- FetchError http read error: overflow
Did someone got a solution ?
I'm on varnish 4.0.2
