Issue Prestashop 8 : very slow and error "504 Gateway Time-out - Nginx"

[ZenPlay]

Server operating system version

CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

18.0.60

Hi.

I have Prestashop 8.1.5 installed and working on VPS server with Plesk Plesk Obsidian Web Admin Edition (Version 18.0.60).

Everything is working fine except :
Changing state of an order is very slow (at least 1 minute) and sometimes this results in a "504 Gateway Time-out - Nginx".
In the Plesk log file, I can see the Nginx error after about 1 minute : "upstream timed out (110: Connection timed out) while reading response header from upstream".

Any idea about the problem ? Thank you.

Note : If I install this PrestaShop 8.1.5 locally with the same data (files and database) on my computer with MAMP server, then changing state is OK.

Hello,
I've just encountered this issue, not with Prestashop, but with Apache x nginx in general. I'm on Plesk 10.0.60, 8 GB RAM, 2 vCPUs, Ubuntu 20.

I've tried these 2 topics, did not work:

Resolved - nginx Fails, Bringing Site Down

Hi, We had a client's site go down, and investigation showed the issue to be with nginx. The log showed multiple entries like this: 3619#0: *22389 upstream timed out (110: Connection timed out) while SSL handshaking to upstream To get the site back up while troubleshooting, we tried to...

Issue - 704710#0: *18394 upstream timed out (110: Connection timed out) while SSL handshaking to upstream

Hi, Over the past week or so we've been getting the following errors across all our nginx sites, causing them to become unresponsive with 504 gateway timeouts. Restarting the nginx service brings them back. We've checked that 127.0.0.1 and the server IPs are added to the Fail2Ban whitelist...

talk.plesk.com

(change PHP "max_execution_time" to 120, then 300, change nginx "proxy_read_timeout", did not work)

I've disabled nginx completely, run Apache only, it was OK. Luckily, my website does not rely on nginx to work.
To disable nginx, just stop the service in Tools & Settings / Service Management.

To investigate further, I've checked Tools & Settings / System Updates / All Packages / search for "nginx", I've found a minor package update:
- On Plesk 18.0.59, this package version is "sw-nginx 1.24.0.3-v.ubuntu.20.04+p18.0.59.2+t240229.1010 (Plesk 18.0.59 packages for focal by Plesk)"
- On Plesk 18.0.60, the package version is "sw-nginx 1.24.0.3-v.ubuntu.20.04+p18.0.60.0+t240313.1332 (Plesk 18.0.60 packages for focal by Plesk)"

I suspect this cause the error "reading response header from upstream" and "SSL handshaking to upstream". But I do not know for sure. Because...
- The website that has problem (18.0.60) has around 2M pageviews, the other (18.0.59) has fewer traffic.

Please check these package from your side, disable nginx temporarily if OK.

Otherwise, I need help also to re-enale nginx.
Thanks.
Alex.
