struct.error: unpack requires a string argument of length 4 #2807
Comments

It seems that file is too large? Small file is no problem. |
|
Does the problem occur when you don't use your proxy, i.e. pass |
|
After a closer look at the code, I'm certain that this error is caused by your proxy mishandling a URL (to be precise, it serves only a couple of bytes instead of the whole file). I'm closing this issue for now. If you want us to reopen it, please post a comment, if possible with the make of the proxy server. |
