Two (2) yahoo accounts - 1 not working correctly

I have two (2) yahoo mail accounts (separate accounts), one (1) that works fine and the other that constantly fails to connect (IMAP). I’ve checked the settings, which are the same as the other yahoo account, run diagnostics which read OK, and even changed the security to an unsecure setting. Any other suggestions as this is very annoying.

Hello,
please send me your IMAP log so we can analyse it. Thank you.

Edit: go to menu Tools->Settings->Advanced->Logging and check “IMAP” under the problematic account. Then restart eM Client, try to simulate the issue and send us (with reference to this topic) the logs using the same logging settings window. Thank you.

Log sent.
