Hi @JohnC2 , thanks for your help on this issue.
We've had multiple customers on BT servers contacting us again about our site being down.
Back in August the issue did seem to be fixed... and was working for multiple customers / colleagues who use BT.
Are you able to check if something has changed or reset with the BT security settings? /
Point us in the right direction for why this might be happening?
Thank you for your help!
