Movable Type Knowledge Base: Bad Protocol 'tcp' When Sending Pings

Question

My activity log reports these errors when trying to send pings, for example: Ping 'http://www.movabletype.org/update/' failed: HTTP error: 500 Can't connect to www.movabletype.org:80 (Bad protocol 'tcp').

Answer

This error typically indicates network problems on your hosting server. You will need to check with your webhost to see if they are blocking any outgoing traffic.

GoDaddy in particular is one host whose servers do not permit these pings to be sent, so users running Movable Type on GoDaddy will not be able to use this feature.

Some users hosting with Earthlink may also experience similar errors when sending pings; Earthlink's version of Perl is too old to support this feature.
