Skip to main content No route to host

A number of bloggers are reporting a new error message, seen when attempting to publish their blog to an external server No route to host

This error is sometimes seen in networking issues in general, and is generally caused by problems like host name or address being incorrect, or maybe a bad DNS server or a bad router. Those are all conditions that lie within Google.

Keeping an open mind, it's possible that the problem may start with something simple, like the Blog URL / FTP Server settings.

Based on the number and variety of reports being published, the problem will probably be resolved by Blogger Support, but getting the problem recognised by them will likely start with help from the bloggers affected identifying the symptom.

If you are experiencing this problem, some basic diagnostic information (whatever you know and can provide) might be useful, to help Blogger Support identify an affinity. You'll find a number of open threads in Blogger Help Group: Publishing Trouble, where your details provided may make a difference.
  • FTP Setting: Blog URL
  • FTP Setting: FTP Server
  • Name of FTP hosting service.
  • Geographic location of FTP hosting service.

(Update 3/8 18:00): Some bloggers have discovered a workaround similar that used for the other currently hot problem. Clear cache, and publish a post as draft.
Cleared cache. Re-set post to draft status and tried again and Bingo! it worked.

I didn't get the connection between this domain and Google Blogger help. I'm still unclear. Anways.

my FTP domain: hosted: location: Toronto Canada.

Is there other information that'd help?

I just noticed it too. Wondered why comments weren't appearing in my blog.
We are switching to word press on our server as of today. I know using word press is stupid but at the same time I cannot afford to keep losing my pictures in blogs, entire blogs disappearing, and now this Java problem with no route to host.

You think Blogger/Google would be able to do this whole FTP upload thing correctly but I be willing to bet it's just because it's Blogger and it's not as important as Gmail or YouTube or the other services Google provides.

Oh well, was fun while it lasted Blogger.

Just for interest, here's a bit about what Blogger techs are dealing with:

No route to host - socket operation was attempted to an unreachable host.

TCP/IP scenario: local network system generates this error if there isn't a default route configured. Typically, though, Winsock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH. The ICMP message means that the router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down).

That's very interesting. What do ARP requests have to do with traffic to distant hosts? Doesn't the default gateway handle this? Are you saying that one of the Google servers doesn't have a valid IP configuration?

Stats Components Are Significant, In Their Own Context

One popular Stats related accessory, which displays pageview information to the public, is the "Popular Posts" gadget.

Popular Posts identifies from 1 to 10 of the most popular posts in the blog, by comparing Stats pageview counts. Optional parts of the display of each post are a snippet of text, and an ever popular thumbnail photo.

Like many Stats features, blog owners have found imaginative uses for "Popular Posts" - and overlook the limitations of the gadget. Both the dynamic nature of Stats, and the timing of the various pageview count recalculations, create confusion, when Popular Posts is examined.

Free Domain Registration By "UNONIC" Is Fraudulent

Blogger blog owners, like everybody else, like to save money.

Some blog owners prefer to save money when registering a custom domain, for their blogs. We've seen several free domain registration services, providing what is claimed to be a two level Top Level Domain "co.xx" (where "xx" == various country codes).

The latest in this ongoing story appears to be "" - and 13 other "top level domains".There is also an additional free service offering third-level .tf domains, under the name United Names Organisation. They occupy 14 second-level domains, including,,, and They are run by the same company as, and are given away as URL redirections.
