ISP IPs pool is blocked by Microsoft - cannot access cloud drive

Hello*.*

I am having trouble accessing a cloud drive shared with me by my employer.

The problem occurs only when using the internet provided by my ISP (in this case, NETIA, Poland).

When I connect using my phone (T-Mobile network) or using VPN, everything works correctly.

I have spoken with my ISP, and the issue is not local to my equipment (computer, operating system, router). I was informed that Microsoft is blocking the pool of IP addresses from which traffic to the cloud drive is coming. They suggest contacting with Microsoft and creating a support ticket.

Please see the details below. Due to asking this question in the community, I am not providing the full IP of the drive.

I would like to ask that you investigate why Microsoft is blocking traffic from my ISP?

Additionally, I was informed by Netia technicians that the problem also occurs for the UPC (Play) ISP.

Technical information below:

**NETIA:**nc -zv 20.XXX.XX.8 445
nc: connectx to 20.XXX.XX.8 port 445 (tcp) failed: Operation timed out

**VPN:**nc -zv 20.XXX.XX.8 445
Connection to 20.XXX.XX.8 port 445 [tcp/microsoft-ds] succeeded!
