Bad connection on BT

[DELIVRABILITY]

Good morning, 

I am deliverability consultant.

I see a pic of bounces on 2 sending domains for one of my client

Log of bounces : bad-connection

Date of this issue : September 16

These are only transactional emails that are sent via these domains.

Nothing has changed since September 16.

This becoming critical for my client.

Could you help me with this please?

Regards,

Isabelle
