I’ve just updated my selfhosted Atuin to 18.19. On the two linux machines I have, everything went fine, but somehow the mac now refuses to login:

Error: error sending request for url (https://my-own-atuin.example/login)

Caused by:
   0: client error (Connect)
   1: bad protocol version

Location:
    crates/atuin-client/src/api_client.rs:149:16

On that machine Atuin is installed with Homebrew; I’ve tried with and without the daemon, but that doesn’t make a difference in the symptoms. I can reach the server using curl:

$ curl https://my-own-atuin.example/healthz
{"status":"healthy"}

Output of atuin doctor:

{
  "atuin": {
    "version": "18.19.0",
    "commit": "",
    "sync": null,
    "sqlite_version": "3.46.0",
    "daemon_enabled": false
  },
  "shell": {

    "default": "zsh",
    "plugins": [
      "atuin"
    ],

  },
  "system": {
    "os": "Darwin",
    "arch": "arm64",
    "version": "26.5.2",

edit I’ve downgraded the mac to atuin 18.18.1 and it works… so that does look like a regression
