Update: Found this proposed solution to the same problem, NEARLY THREE YEARS LATER. At first, it seemed to work, but then the problem quickly emerged again. Of course, DH will blame Blogger and Blogger will blame DH. Given the recent week of hell at Blogger, the benefit of the blame currently lies with Blogger. Still, it would be nice to have a once-and-for-all explanation and solution for this common intermittent annoyance.
Here is Blogger’s Excuse:
Socket Not Established
"This error most commonly occurs when Blogger is set to publish via SFTP to a server that does not support that. Try changing your publishing settings to regular FTP and see if that fixes it. If not, contact your hosting provider to find out more about the error."
Obviously that’s completely bogus, because SFTP was working just fine for months and months. If anyone can suggest a fairly painless way to transfer a blog from Blogger to Wordpress, here on DH, that might be one solution. My bet is that transferring content between blogging platforms would be somewhat of a foo; but perhaps readers know of tools I’ve not yet discovered.
