What are you putting into the Blossom Servers box?  I put "cdn.satellite.earth" and I get `402 Payment Required` which is as expected.  Don't put in URLs like "https://cdn.satellite.earth/upload", it doesn't want URLs because blossom support may include other URLs like /mirror.   You can however specify a port. 

 Also, I've been pushing fixes up until about an hour ago so pull the latest. 

 Based on BUD-03, I may have to change this anyways.  It wants the full URL of the base.  Changes will be coming. 

 ＯＫ！ありがとう👍 

 You can now put in either hostnames or URLs (just pushed).  If you put a URL with a scheme, it will keep/honor the scheme.  If you put a path/query/fragment it will ignore those.  So you can even leave the "/upload" and it will still work. 

 https://cdn.satellite.earth/upload → HTTP (reqwest) error: error sending request for url (https://https//cdn.satellite.earth/upload/upload)
cdn.satellite.earth/upload → Blossom error: 404 Not Found
cdn.satellite.earth → Blossom error: 401 Unauthorized

@fiatjaf
You're using https://satellite.earth/cdn/upload too, right? Could you try it out for me? 

 I put the fix on unstable.  I guess I can copy it to master.  There.  Pull and try again. 

 cdn.satellite.earth/upload → Uploading...
It remains stuck on "Uploading..." 

 Thanks for helping me find all the ways it could fail.  I've pushed another fix (the 13th fix since I thought I was finished!)

cdn.satellite.earth/upload → Invalid URI: invalid format
cdn.satellite.earth → Blossom error: 404 Not Found
https://cdn.satellite.earth/upload → Blossom error: 404 Not Found 

 That first one isn't a hostname and it isn't a URL either.  So I don't think I could make that one work too easily.

The second two are being understood but there is some other problem.  Only I don't understand what it is yet.  404 Not Found is a strange error for an upload.

Could you try "https://blossom.primal.net" or "https://blossom.nostr.hu"  and see if they also give you a 404? 

 https://blossom.primal.net →

https://blossom.nostr.hu → Blossom error: 404 Not Found 

cdn.hzrd149.com → Blossom error: 404 Not Found 

The cdn.hzrd149.com that was working well in the morning has also become a Blossom error: 404 Not Found. Only https://blossom.primal.net is working well. 

 Ok I pushed another fix (it was putting a double-slash in the URL).  I also merged in a fix to kind-1111 notes which will rebuild relationships.
