Hey @the-qubit-guy , unfortunately no, they have recently introduced this on Enterprise workspaces (about a month or so), and there's no known workaround yet. I tried to address it by using different User Agent in the latest version, but as you're getting this error, it seems that it did not help. Their detection criteria are unknown, can only guess that it may be the pattern of requests, or the rate. Let me know if you are able to find a workaround, that would be of help to many. |

Hi there. In my Slack MCP Server have in most of cases successfully mitigated this issue by faking TLS handshakes. /cc @rusq, also thank you for your library it is a great basis for that proj! :) I hope my comment will help to improve the core library |

@rusq I wasn't brave enough to change this directly in slackdump, instead wrapped into my own tiny utility gh-slackdump. But if you were open to it, I can definitely try changing this inside slackdump. Give me a week or so. |

It's ok, I'll have a look - it won't be in slackdump repo, but rusq/chttp which provides a "cooked client" - http.Client with cookies. |

@wham That's a pretty sophisticated cookie parser you got over there :) |

Thanks for trying it out @Shegox ! Looks like there's still some areas for improvement. List channels is quite aggressive in the "edge" implementation used on enterprise workspaces — I'll see if something can be done with it. But good news that it doesn't get kicked out straight away. :) |

I just tested it with the latest
mastercommit (bb5571c) and it works now without logging myself out.The
go run ./cmd/slackdump resumewhich normally suspended my session after a few seconds works now seemless.The emoji dump worked as well, the channel listing eventuelly kicked me out, but that can be as well just because we have a lot of channels. :)
