By default, the OpenLiteSpeed Web Server does not know the MIME type (application/json) of the “.webmanifest” manifest files of Progressive Web Applications (PWA), so the mentioned files are served with the “application/octet-stream” MIME type that actually represents unknown binary files.
a) Configuring
Open the /usr/local/lsws/conf/mime.properties file on your favorite text editor with superuser privileges and add the following line mentioning the specific MIME type of your desired file.webmanifest = application/json
b) Restarting
Changes will take effect after you give the OpenLiteSpeed Web Server a graceful restart. (Graceful restart ensures zero downtime.)
- In case of its WebAdmin Console: Just click on Graceful Restart icon and then proceed to Yes.
- In case of systemd:
sudo systemctl restart openlitespeed.serviceorsudo systemctl restart lsws.service
