Can't log anymore in a plex account from a friend

Plex Media Server

I’ve been sharing a plex account for several years with a friend. I started having problems connecting from the PC. It says that the password and email are not recognized. On the tablet, it continued to work, but failed too. I read on the forum that it could be a problem with the Internet provider, but I can’t solve it.Plex Media Server Logs_2020-07-26_13-00-53.zip (585.0 KB)

I made an update and I send the new logs.Plex Media Server Logs_2020-07-26_14-11-02.zip (1.9 MB)

There is no need to share accounts.
Don’t do it.

I see that it’s the instructions for sharing an account, but I don’t share the account. I use the same email and password as my friend, but lately, I can’t login, even though he hasn’t changed the data.
