[Bug]: Unexpectedly getting a 404 when registering to my server

[axelson]

What did you expect to happen?

I expected that after setting the IP address of my server where atuin is running that I would be able to login and register from my clients.

What happened?

I've tracked this down. The issue is related to configuration. Specifically:

• From https://docs.atuin.sh/self-hosting/server-setup/ I can see that atuin uses a default port of 8888
• From the self-hosting usage page https://docs.atuin.sh/self-hosting/usage/ I followed the "config" link to https://docs.atuin.sh/configuration/config/#sync_address
• That told me "The address of the server to sync with!" and gave the example of sync_address = "https://api.atuin.sh"
• So I set my local server in my ~/.config/atuin/config.toml as sync_address = "http://192.168.1.2"
• However then when I run atuin register I get the 404 mentioned above
• In troubleshooting this I tried setting sync_address = "http://192.168.1.2:8888" and then registering and syncing worked

So I think the bug is either:

• The docs should be updated to include the port number (specifically the https://docs.atuin.sh/configuration/config/#sync_address page)
• The default port is incorrect/doesn't match between server and client (it's not clear what default port my client is using)
  • But after using strace it appears that the default client port is actually 80, not 8888

Additionally I think it would be helpful if:

• The register/login commands contacted the server to verify that it is a compatible atuin server before taking user input
• The register command printed out the server that you're registering to
  • I want to use my own server and I wasn't sure if i had configured the sync_address correctly and from the console output it wasn't clear if I was connecting to my server or the default server
• The 404 error message included the hostname, port and path that 404'd
