because i remember 406 from wayback, i had to look this up and see what the deal was with it. i dont have your domain, or i would login and see if it gave me the same error. i would go out on a branch and bet that its a problem with your host. where are you hosted?
here is what i found about 406 Errors:
Introduction
A client (e.g. your Web browser or our CheckUpDown robot) can
indicate to the Web server characteristics of the data it will accept back from
the Web server. This is done using 'accept headers' of the following types:
- Accept: The MIME types accepted by the client. For example, a
browser may only accept back types of data (HTML files, GIF files etc.) it
knows how to process.
- Accept-Charset: The character sets accepted by the client.
- Accept-Encoding: The data encoding accepted by the client
e.g. the file formats it understands.
- Accept-Language: The natural languages (English, German etc.)
accepted by the client.
- Accept-Ranges: Whether the client accepts ranges of bytes
from the resource i.e. a portion of the resource.
If the Web server detects that the data it wants to return is
not acceptable to the client, it returns a header containing the 406 error
code.
406 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes
through the following cycle:
- Obtain an IP address from the IP name of your site (your site
URL without the leading 'http://'). This lookup (conversion of IP name to IP
address) is provided by domain name servers (DNSs).
- Open an IP socket connection to that IP address.
- Write an HTTP data stream through that socket.
- Receive an HTTP data stream back from your Web server in
response. This data stream contains status codes whose values are determined by
the HTTP protocol. Parse this data stream for status codes and other useful
information.
This error occurs in the final step above when the client
receives an HTTP status code that it recognises as '406'.
Resolving 406 errors - general
This error occurs very infrequently in Web browsers, because
most browsers will accept any data returned from your Web server.
If the client is not a Web browser, then anyone can only
investigate the problem by looking at the Accept headers generated by the
client system and the data stream returned by the Web server. If you do not
have access to the source code for these systems, the only thing you can do is
refer the problem to technical support people at the companies that developed
the systems.
Resolving 406 errors - CheckUpDown
This error should simply never occur in your CheckUpDown
account. If it does, it typically indicates defective programming of our
systems or of the Web server which manages your site. We do not use accept
headers at all, so there is no reason for your Web server to generate a 406
error.
i know this may not help much, but it says something is going on with the browser and the data it is trying to serve back to you.
