Help Needed With Connection Error On Google Merchant Feed

Hi Gyus,

Hoping you can help with a connection error I’m having with a Google Merchant Centre feed. I have an ubuntu 18.04 / nginx web server on Digital Ocean.

The scheduled fetch was working perfectly well so I know the URL is ok - I got Spinup WP to manage the server and since then the feed has stopped working

I have asked them and they assure me that wp-load is not blocked but unfortunately are unwilling to go any further to assist me with support - they told me to dig into it using curl -l

Here’s what I’ve discovered:

curl -l "https://tande.co.nz/wp-load.php?security_token=*removed*&export_id=25&action=get_data"

File starts to download but stops mid way through with the following error:

(92) HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)

I checked the error.log and found the Following error

2020/07/09 08:28:02 [crit] 18167#18167: *118102 open() "/var/lib/nginx/fastcgi/2/94/0000000942" failed (13: Permission denied) while reading upstream, client: , server: tande.co.nz, request: "GET /wp-load.php?security_token=&export_id=25&action=get_data HTTP/2.0", upstream: "fastcgi://unix:/run/php/php7.4-tande.sock:", host: "tande.co.nz", referrer: "https://tande.co.nz/wp-admin/admin.php?page=pmxe-admin-manage&id=25&action=google_merchants_info”

It looks to me like permission is denied to the /var/lib/nginx/fastcgi directory

So, following this guide

https://gurdeep.ninja/nginx-500-error-varlibnginxtmpfastcgi-failed-13-permission-denied/

I looked at the permissions as follows:

matt@tande: /tande.co.nz$ sudo ls -lath /var/lib/nginx 
[sudo] password for matt: 
total 48K
drwx------ 102 tande    tande 4.0K Jun  3 21:03 0

drwx------  12 www-data root  4.0K May 30 19:10 .
drwxr-xr-x   7 root     root  4.0K May 26 15:22

I ran

sudo chown www-data:root /var/lib/nginx 

as per suggestion but this has not resolved the issue. Permissions now look like following:

matt@tande: /tande.co.nz$ sudo ls -lath /var/lib/nginx 
[sudo] password for matt: 
total 48K
drwx------ 102 tande    tande 4.0K Jun  3 21:03 0

drwx------  12 www-data root  4.0K May 30 19:10 .
drwxr-xr-x   7 www-data root  4.0K May 26 15:22

Can you help me with what to try next? Please let me know if you need further info that will help you assist

Many thanks in advance

Matt
