The PR_END_OF_FILE ERROR is a known glitch with Mozilla Firefox where it will display that error if it is unable to establish a secure connection after trying all listed cipher suites. In this case, the reason for the inability to establish a secure connection was that GoDaddy was temporarily redirecting Sietch traffic due to a technical issue with DNS renewal. Other browsers were able to handle this change gracefully; Firefox spazzed out.
This is one of many reasons that we at Comstar do not recommend the use of so-called "open source" software when connecting to HPG networks.
