The error your friend received probably has no relation (I think) because it is related to HTTP requests in SAMP. Look at this page: https://wiki.sa-mp.com/wiki/HTTP for more information. You can see the error output in the code at that page and all error codes, too.

Error code 6 means HTTP_ERROR_MALFORMED_RESPONSE. And malformed response simply stands for a bad response that can becaused by several things like a bad connection, something might be wrong with the server or something else.

I'm not a game server administrator or atleast not for SAMP. So I'm out here since your fresh installed server without any plugins or similar is also crashing without any error output. No idea really. Sorry.
