Ip-*-*-*-*.eu-west-1.compute.internal tyk[20069]: 2020/05/04 14:07:56 http: TLS handshake error from *.*.*.*:56836: tls: no certificates configured

Regarding the ALB ssl termination it does not validate the certificate but still enable https connection to its target groups just checking whether certificate is present or not and this where i was getting the error.
