Hi,
After migrating our websites to a new server running CyberPanel with LiteSpeed Enterprise, we experience blank pages on the first visit. Reloading makes the pages display correctly.
The issue affects multiple websites and occurs across different browsers and networks, including mobile data.
In browser DevTools:
The main HTML document returns HTTP 200 quickly.
Some resources load normally over HTTP/2.
Other CSS, JavaScript, and image requests remain pending with 0 kB transferred for over 30 seconds.
These requests show “Stalled” in Timing, with empty Protocol and Remote Address columns.
Opening an affected CSS file directly works after a short delay.
Could this be related to per-client throttling, connection limits, or HTTP/2 handling?
Do any one else had this issue? Any suggestions on how to resolve?
