error: redirect_uri_mismatch

oops! something went wrong

error: redirect_uri_mismatch
error_description: redirect_uri did not match any of the client's registered redirect_uris
state: kjkmdskdmsmmsmdslmdlsm

OAuth with Swan is not working and throws a redirect_uri_mismatch error instead.

Steps To Reproduce

1. Log in to specter desktop, e.g. ‘http://umbrel.local:25441’
2. Click on ‘+ Choose plugins’
3. Click on ‘Swan’
4. Click on ‘Existing Swan users’
5. Click on ‘Link your account’
6. New tab opens presenting the error shown in the screenshot https://api.swanbitcoin.com/oidc/auth?client_id=specter&redirect_uri=http://umbrel.local:25441/svc/swan/oauth2/callback&response_type=code&response_mode=query&code_challenge=<redacted>&code_challenge_method=S256&state=kjkmdskdmsmmsmdslmdlsm&scope=offline_access%20v1%20write:vendor_wallet%20read:vendor_wallet%20write:automatic_withdrawal%20read:automatic_withdrawal&prompt=consent

Expected behavior This has worked at least once at some point in a version of specter desktop prior to updating to 1.13.1. I don’t know exactly in which version this regression was introduced though. Auto-withdrawals from Swan to Specter had been working for this account for quite some time. Eventually the auto-withdrawal stopped working which is why I attempted to re-connect the plugin.

Screenshots

• Where is your node running: umbrel
• Where is your specter running: umbrel
• If you’re running a binary, which OS: I don’t think it matters, but I’m also running specterd hwibridge on macOS since I access specter remotely
• Browser: any, I tried Chrome, Brave, Safari and Edge
• Specter Version: 1.13.1

@aphex3k we’ve identified the issue, it is on the Swan server side. I will tag you here, once it is resolved. Thanks for your patience and for bringing it to our attention!

Just a general note: You cannot expect to setup the integration on one specter and then use it on another instance. It’s difficult for me to understand this issue as IMHO, it should never have worked on an umbrel.

I’ve been using the same specter desktop instance on my umbrel. I’ve not moved it or anything. I just updated the docker containers to whatever was latest at the time and set up the Swan extension on the first version that it had available in a non-pre version.
