Means that one of the TLS/SSL packets had an error in it.

bad_record_mac

This alert is returned if a record is received with an incorrect
MAC. This alert also MUST be returned if an alert is sent because
a TLSCiphertext decrypted in an invalid way: either it wasn’t an
even multiple of the block length, or its padding values, when
checked, weren’t correct. This message is always fatal and should
never be observed in communication between proper implementations
(except when messages were corrupted in the network).

It is probably a networking error of some kind, so I wouldn’t worry about it unless you get it a lot.
