'Google Chrome returning 503 Service Unavailable

I have been having an issue lately with Google Chrome. Some sites, seems to be completely random, are returning a 503 Service Unavailable error message. The last one I received was from my hosting provider when trying to access my CPanel. I can access the same URL completely fine in Firefox or IE. It seems to be isolated to Chrome.

I have tried the following:

  1. Disabled all extensions
  2. Logged in/out of my Google account
  3. Cleared all cache and history

So far, nothing seems to correct the issue. It's becoming more and more aggravating from what was once a pretty reliable browser.

I am running:

Windows 7 Chrome Version 36.0.1985.143 m

I was hitting the same issue. Mostly, it would occur on intranet sites at work, but it happened with a few exterior sites. Loading in IE Tab would work fine.

I was able to solve the issue by upgrading to 64-bit Chrome. I'm not sure why that fixed it, but I think it had something to do with a conflict between Java and Chrome (It looks like I have both 64bit and 32bit Java installed side-by-side).

My solution:

  1. Uninstall Chrome with clear personal data option selected
  2. Install Chrome again but without admin right (install for your personal user)
  3. Use Chrome as normal
