Budget: 9000 UAH Deadline: 3 days
I can take this on. My rate is 1500 UAH per hour, and for this task, I would estimate around 6-10 hours after a brief diagnosis. If the problem is only with the OAuth settings, redirect URI, scopes, application mode, or production access - this usually takes 1-3 days.
Look, there’s a nuance here... the fact that the login works only with test accounts is very similar to applications in Google, Meta, or TikTok that are not fully set up for production, or to different environments for local and production settings. We will need to check the Next.js code, callbacks, domains, environment variables, and application statuses in the providers' dashboards.
> Question 1 - is your authorization done through NextAuth/Auth.js, Firebase, Supabase, or a custom implementation?
> Question 2 - do the errors appear after selecting an account, on the callback page, or at the stage of opening the provider's window?
We have experience in services with authorization, integrations, and business logic, where stability is important, not just logging in somewhere once =)

So here’s the thing - I would first conduct a technical diagnosis, then provide a precise list of causes and fixes. But we can keep it simple; if everything hinges on the providers' settings - we’ll close it quickly.
