soap:Server was unable to process request.--->Value does not fall within the expected range.

Hi,

Sometimes our URL say http://servername:portno doesn’t work due to network issue.

Whereas http://localhost:portno works out, but when try to edit master file through SharePoint designer we may get the following issue.



After clicking on Details button, we can see the following message.



At that moment,this would be the show stopper to move ahead.
Finally from my trainer I got the below link and made the changes accordingly.
After doing this I was able to make the changes in the master page.

Hope now your way would be clear to edit the master file of the file.
