Issue NGINX crash loop on chunked data

Lcf

New Pleskian
Hi,

I'm using Plesk for my website, with OVH as reseller, but unfortunately, its support doens't keep their 24/7/365 promise... (down since 3 days)

My website is a technical demo, for an open source library, requiring to send some chunked data form the server, to illustrate how my library handles the servent-sent events.

If I only load my page, without events, it works... but when I call the event stream, it crashes NGINX repeatedly, until the Apache crash.

1404#0: *9 upstream sent invalid chunked response while reading upstream nginx error
1404#0: *4 upstream sent invalid chunked response while reading upstream nginx error
1404#0: *22 upstream sent invalid chunked response while reading upstream nginx error
1404#0: *25 upstream sent invalid chunked response while reading upstream nginx error
1404#0: *28 upstream sent invalid chunked response while reading upstream nginx error
503 GET /events HTTP/1.0
(70007)The timeout specified has expired: AH01075: Error dispatching request to : (polling) Apache error

Is there something I can made myself to solve it, please?

You could try to add this directive to the Nginx configuration:

Code:
proxy_http_version 1.1
proxy_set_header Connection ""
 
Thanks Peter for your response.

But, is it possible to define that in the Plesk interface or by a local configuration file?

Because, I don't have any root access on the server, it's an OVH installed Plesk instance.
 
Ok, I only have to wait an hypothetical response from their support. :|

Thanks anyway to you.
