OAuth2 - Iframe/debugger issue?

Hi and hello, i’ve been trying to connect to an api with auth2 (via the workflow; Login with API). But ive been running into an issue. Basically, it keeps saying i havn’t configured the plugin correctly - I also get this error:

“General error: API Connector error: the call bTKth.bTKvf is missing, please reinitialize your calls.”

I have a suspicion that it might have to do with the api/auth im trying to connect to. Doesn’t allow iFrames and the debugger, is needed for first time connection

Am I out of luck or is there a workaround?
