Hi I have exactly the same issue, details as follows:
server environment: LiteSpeed Web server
LiteSpeed Cache Image Optimisation: v2.9.8.5
After clicking “Send Optimisation Request” I get the message: Images requested: 1 group (7 images), the stats shows as “Communicated with LiteSpeed Image Optimisation Server successfully”. After a while I get the message: “Images failed to notify: 7”.
I left it overnight assuming the LiteSpeed Image Optimisation Server had a high demand, then checked in the morning to see if an image pull had occurred by chron, but no change at all, still the same message: “Images failed to notify: 7”.
Could this be some kind of firewall issue? WHat can I try?
