Can't get email from Gmail - Invalid server certificate

Hello all,

Today I had lunch at my daughter's and she asked me to take a look at 
her The Bat!, because from some time ago (does not remember how log) 
she can't retrieve POP email from her Gmail account. 
She is still using version 4.2.44, and this is what she gets in the 
account log:

 22/01/2023, 16:18:35: FETCH - receiving mail messages

!22/01/2023, 16:18:36: FETCH - TLS handshake failure. Invalid server certificate (This certificate has expired).

Does anyone know what the problem may be and how to overcome it? I'd appreciate any help.
TIA.
