We're experiencing the same issue here. Reports from multiple clients over the last few days. Surely enough checking the logs yields an invalid_credentials error.
Trouble is, we can't faithfully reproduce the issue from our network, but clients are reporting failures to authenticate every time they try!
Have contacted Instagram for an update. Anyone else still experiencing the issue?
I think everyone posted, replied under this thread (and many other stackoverflow threads) experienced the same issue. The issue seemed resolved for us just yesterday for a day, but today, it started acting up again, had to switch up wifi to log into Instagram. We also added email login after this incident.
