Any clues as to what the message in the title means?

To reproduce this, I have removed ~/.config/iamb, ~/.local/share/iamb, and ~/.cache/iamb -- just like it would be if I had never run iamb before. With a sufficient timeout, I can sync up my matrix account with fedora.im. I can see rooms and spaces and such -- it all looks quite nice, really; thank you!

However, if I quit iamb, and then run it again, I get the following:

$ ~/projects/iamb/target/debug/iamb

  • Logging in for @
  • Syncing...
    the server returned an error: [404]

If I remove all the files again, I can sync up again, but have to go through the SSO process again. And if I quit iamb, I'm back to .

I've attached a debug log but with my matrix account redacted. I would dig further, but I'm still a rust n00b.

additional info: no verification had taken place; however, even if verification was successful, and the final tab is :quit, I get the same message

It looks like there may be something odd going on with which server it's trying to connect to. I can see that it's getting back 404 responses from chat.fedoraproject.org

But it looks like that's not the right Matrix homeserver URL:

% curl https://fedoraproject.org/.well-known/matrix/client
{  
   "m.homeserver": {
       "base_url": "https://fedoraproject.ems.host"
   },
   "m.identity_server": {
       "base_url": "https://vector.im"
   },
   "org.matrix.msc3575.proxy": {
       "url": "https://fedoraproject.ems.host"
   }
}

You might want to try setting your profile to have an explicit homeserver and see if that fixes it:

[profiles.PROFILENAME]
user_id = "@whatever:fedoraproject.org"
url = "https://fedoraproject.ems.host"

I've had the same error message while trying to login to my matrix account at utwente.io. For me, the following solved it: usually, they (utwente) automatically redirect the server url from https://utwente.io to the actual address https://matrix.utwente.io. But it seems that this automatism does not work with iamb. After I changed the url in the iamb configfile to https://matrix.utwente.io, the login worked without issues. Maybe there is a similar issue with your matrix server.
