Hi,

I have this problem - some of the websites load really slowly, and when they finish loading, there is no any stylesheet or design, just plain text and links. Most of the websites are fine though. What could cause these few websites to load so slowly and incomplete? On other computers they load fine.

Thanks

Brief diagnostic note based on the thread: when pages render as plain text while static resources (CSS/JS/images) return HTTP 502 from their static-content domain, the browser is receiving a “bad gateway” response for those assets. Because reports the same network serves other machines correctly, the problem is most likely local to the affected PC (wrong DNS/hosts entry, a local proxy/filter or AV web-intercept, an IPv6/route problem, or a browser-extension/proxy that only that machine uses). This expands on ’s suggestion to inspect HTTP traffic and clarifies why the suggestions from , and (site changes or bandwidth saturation) are possible but less likely when other hosts load the site fine.

Practical, ordered checks to isolate the fault:

  • Open the browser DevTools (F12) -> Network -> Preserve log -> reload the page and note which requests show 502 and their request URLs/hosts.
  • Capture a failing request as cURL for inspection and repeatable testing.
  • Compare name resolution and route between a working machine and the broken one.

Example commands to run (replace the domain/path with the failing static host):

ipconfig /flushdns
nslookup static.example.com
tracert static.example.com
curl -v -I "http://static.example.com/path/to/style.css"

What to look for and next steps:

  • If nslookup returns different IPs between machines, treat it as a DNS problem (try changing to 8.8.8.8 or 1.1.1.1 temporarily).
  • If tracert diverges or stalls, it points to routing/ISP/CDN edge issues.
  • If curl shows an HTTP 502 returned by an intermediate proxy (headers may identify a CDN or appliance), the request is being proxied/filtered before reaching the origin.
  • If disabling local AV/web-shield or removing a proxy fixes the issue, that component is the culprit.
  • As a quick isolation step, test the same URL over a VPN or a phone tether — if it works there, the issue is on the local/ISP path.

If the above still fails, gather the DevTools network log, the cURL dump, nslookup and tracert outputs with timestamps and provide them to the site admin or the ISP for investigation.

maybe they are reconstracting the site or the sites that u want to open were set not to open on your computer? try to check you setting :)

Hmm, did some tests and it seems those sites are giving 502 bad gateway error on their static content domain. On other computers they seem to load fine (from the same network). Any suggestions?

Are you running any type of filtering software? For example, when you access a web page, in some cases, you are downloading content from several sources. Possibly anti-malware or filtering malfunctioning causing some of the content such as the stylesheets not to load?

If you know how to examine HTTP traffic, you could use browsers such as Chrome, IE 9, or Firefox which you can install debugging tools to see what's happening.

Try checking it again after few days. Maybe they are doing some minor changes. Also consider your internet connection maybe it affects the loading of the page.

This happens when your internet connection is VERY SLOW or you are currently ACTIVELY downloading something else (or watching Porn) ..

: or uploading. Mostly because the brouser can't return the ack to the sender.
