Dear TeamViewer Support,
We are experiencing consistent connectivity issues to TeamViewer services from the following IP range:
Prefix: [removed per Community Guidelines]
Observations:
to check with Team Viewer Germany to check any blocking for prefixes [removed per Community Guidelines]. Suspect prefixes blocked by TeamViewer
No response is received from the final hops, suggesting possible ICMP/TCP filtering or blocking.
The issue is not present when using different ISP networks, indicating a potential IP-based filtering policy.
Request:
Could you please verify whether the IP prefix [removed per Community Guidelines] is subject to any firewall rules, blacklisting, or traffic filtering on your side?
If blocking is confirmed, we would appreciate:
Details about the nature and reason for the block.
Steps to request whitelisting or resolution.
