"Unusable" is the explanation for a list of different "unknown" errors. They could also result from an errors in Phex. To get the real reason each communication protocol would need to be deeper analyzed. Here are some possible error cases:
- The host send HTTP header data that is invalid or couldn't be understand enough by Phex to do a download.
- The host sends multiple different identification headers (containing the servent vendor name), some spammers had this bug.
- The host returns 401 (unauthorized) or 403 (forbidden) errors and is a Gnutella 2 servent that disabled Gnutella downloads. Returns: "Network Disabled"
- The host returns 401 or 403 errors with unknown reason.
- The host returns 500 (internal server error)
