I lost two accounts in the last update. I researched my logs and maybe I know why.

Hi, guys!

I used only the pokefarmer. All the time I had only three captchas in all four used accounts. One of these accounts was legitimate and used in Pokefarmer during the last 4 days.
When there was the last update, I started using the accounts on my phone with fake GPS. All works ok. I have not used the Pokefarmer updates. With absolute certainty. I did not turn on the PC.
Suddenly, still using the accounts on the phone, two of them began to present the damn login error. At first I thought it was due to problems on the Niantic server. In any device I logged in, the situation was the same: two completed the login process and were functional; Two others had a login failure.
I've seen many people on various Discord channels with the same problem. It did not matter if it was the Pokefarmer or any other bot. All were discussing similar situations. I found it interesting that several moderators said categorically that were problems in the Niantic server and / or that there was no confirmation that it was really a ban wave.
I was curious why only those two accounts had the login problem. All accounts had the same settings in the Pokefarmer. All were used alternately every day, whether while the Pokefarmer was working or using FlyGPS.
Looking at the Pokefarmer logs, I discovered that the two accounts that have "login problems" were used in the early hours of January 19th. It was on this day that the Pokefamer servers were paused.

Well, I not found but no relevant fact. If this is the explanation for the "login failure" then someone did not pause the Pokefarmer service in time ...

 

now this is a good question xD
