Error "Password may have been changed by the account owner..."

Hey guys! I've been running 30 accounts on Follow Liker for the last few months and everything had been running smoothly. Recently I started getting a few Errors on accounts that said the password is invalid. When I logged into the account, it said "Password may have been changed by the account owner..." This happened to 5 out of the 30 accounts.

The passwords were not actually changed. A few hours later the password would be working again without doing a password reset. In one case, the original password had to be changed.

Details:
- This happened on both new, and aged accounts (brand new, and 3 years old).
- This happened to accounts with aggressive and non aggressive settings. (1000 daily follows and 350 daily follows respectively)
- It happened to accounts with, and without proxies. (4 accounts per proxy, one account was not proxied)
- 3/5 of the accounts have an active user posting from their mobile device, the other two are being accessed only by Follow Liker.
- I only follow/unfollow, nothing else.

I NEED to make sure this does not end up banning any of these accounts please help!

This can happen to any account. It has happened to many of my accounts, i have not been botting on them or done any illegal activities on instagram. No need to worry

happens to me too, super random

Happened that to me today, I don't think this is something we should worry about
