Hi,
Do you know how long it takes to show the 503 error when downloading the 800mb file?
Maybe you can try to increase wsgiDefaults values, e.g. env, initTimeout, and extMaxIdleTime, from the httpd_config.conf.
HI, I launched a fresh Ubuntu 18 server and was not able to reproduce it. Could you raise a ticket to us support@litespeedtech.com with this forum link appended?
Like this forum said https://forum.openlitespeed.org/threads/hsts-strict-transport-security-preload-https-ssl-header-only.4083/, create a separate HTTPS virtual host and set the header in the context of it.
You will do the mapping after the Virtual host created.
Go to Listener > your HTTPS...
certbot renew --force-renew --deploy-hook "systemctl restart lsws"
According to the log LSWS restarts fine when --force-renew is used.
Looks good to me, let's see if it will work on the next renewal.
