Hi!
I'm maintaining many bots on Hungarian Wikipedia, they are written in C# using DotNetWikiBot. Lately I randomly get 417 errors from the server (for example at login, at saving pages). If I repeat the request caused 417 again a sec later, it probably works. (Formerly there were no problems at all.) The problem exists using cable connection at home, and the university's network. I haven't found any useful information about 417 on the net, how to avoid it.
Could you give me some information?
Googling "417 Expectation Failed" (Wikipedia gave me the text to go with that status code) gave me some rough descriptions of what the error means. Apparently you sent an "Expect" command to the server that it couldn't comply with - does the error message give any details about what the "Expect" was? It sounds like it's probably a bug with DotNetWikiBot, so you should contact the author.
