Password Managaer and Starling 2FA, firewall issue

Hello,

I am using PM 5.8 with Starling 2FA. I have an issue configuring firewall.

I noticed that PM makes https request to sts.cloud.oneidentity.com and 2faclient.cloud.oneidentity.com.

I cannot oper firewall for IPs because I think IPs change in time.

There is a way to use a proxy?

This is a big issue. Backend has no direct access to internet.

Thanks
