Eveything has been going smoothly for months but the last week, I have been getting users getting errors uploading images over 2mb and today, I couldn’t upload or download large CSV files from multiple sites I host.
See an error like this in the error.log each time. Below is an example but different websites and different plugins do the same thing. No changes to my php or nginx configs. Everything is well above 2-3mb limit.
2022/04/15 11:58:17 [crit] 1068#1068: *1722073 open() “/var/cache/nginx/fastcgi_temp/7/12/0000000127” failed (13: Permission denied) while reading upstream, client: 18.104.22.168, server: siteandinsight.com, request: “GET /wp-admin/tools.php?page=acui&tab=export&nonce=96b5cb73cb&action=download_user_csv&filename=user-export.csv HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.4-fpm-siteandinsight.com.sock:”, host: “www.siteandinsight.com”, referrer: “Log In ‹ Site & Insight — WordPress”
On the sites themselves, most of the time I get
"Internal Server Error
Oops! Something went wrong.
The server encountered an internal error or misconfiguration and was unable to complete your request.
Error Code: 500
Update: Just tried with a file that 500kb and it had the issue.
Any help would be great!
