FETCH - TLS protocol error: Internal error BuildClientKeyExchange

Is it your BT issue - #0001989: Gmail does not work with TB any more ? If not, support it.

It may be that the mails are checked by an AV software?
Please disable mail verification. I have had the same problem.

Briard had the same error in the thread "9.1.12 GMail kann nicht abgerufen werden". The command line parameter /TLS_DISABLE_PERFECT_FORWARD_SECRECY helped.

With the / TLS_DISABLE_ECDSA parameter it works!

Grazie GwenDragon

You are welcome

This issue is resolved in The Bat! v9.1.16. Download page: https://www.ritlabs.com/en/products/thebat/download.php

In an ECDSA signature, if a hash function had larger digest length (in bits) than the field size (which is not a good practice), The Bat! treated these signatures as invalid. It might lead to invalid ECC certificates, e.g. signed by "sha512ECDSA" algorithm. It might also lead to the following error: "TLS protocol error: Internal error BuildClientKeyExchange".
