Audiotool board archive

I am unable to renew soundcloud credentials, nor use the "login with soundcloud" feature.
This stops me from exporting directly from audiotool to soundcloud. When trying to login with soundcloud, soundcloud gives a "invalid uri" message. I have tried signing out and logging back into both websites multiple times, and it did not fix the issue. The error message previously referred to reads as follows:

Something went wrong (redirect_uri_mismatch)

The redirection URI provided does not match a pre-registered value.
