Describe the bug
A clear and concise description of what the bug is.
Everything goes perfectly until the test auth. where it produces a auth link for mal or anilist. when I open it it asks for permission by clicking Allow. But when I click allow, an error message occurs "Error processing request.". It's happening for both MAL and Ani;ist.
To Reproduce
Steps to reproduce the behavior:
Follow the instructions of the plugin and make api and generate auth link.
open the link, click Allow
it'll give "Error processing request."

Desktop (please complete the following information):

• Browser Chrome
• Jellyfin version 10.8.12
• Plugin version 2.9

What redirect URL are you using? From your logs (you may want to edit/delete the attached file, as it may contain some information you do not want to keep public) I can tell it should probably be http://localhost:8096/AniSync/apiUrlTest
Did you also test the redirect URL to confirm it is correct?

Hello just commenting to say that I have run into the same issue as above. Sometimes the link brings up a login prompt and fails with the message "invalid client" when cancel is hit; I managed to get to the above mentioned screen once as well without having to log in where you would hit allow on MAL but then it returns "error processing request". The ApiUrlTest passes.

I believe this would be the relevant error found in the jellyfin logs:
[ERR] [36] Jellyfin.Server.Middleware.ExceptionMiddleware: Error processing request: "Could not retrieve Mal token: Unauthorized - Unauthorized". URL "GET" "/AniSync/authCallback".

The status code I have seen in various places is "400"

Edit:
I'm also running my jellyfin through docker and got this working but I tried a couple different things at once so I'm not honestly sure which part got it working. I think adding the docker url to the apiconfig in MAL may have been the fix but I'm not sure if that was actually the case.
