Does this happen only in these 2 VPCs? After how long do you notice the
connectivity is lost?
What is different compared to other VPCs where this does not happen?

Hello all,
We have observed recurring issue that has been observed recently in the
CloudStack environment we use for hosting virtual machines.
Specifically, we have identified that certain Virtual Routers lose
internet
connectivity, which causes disruptions to services such as VPNs and
other
network-dependent functions. This issue was first noticed with the
infrastructure of the customer1 vpc. For the customer2 vpc case, we
resolved the issue by recreating the VPC along with the associated
guest
networks.
1. Connectivity Issues:
Check IP Ranges and Netmasks:
Connectivity Checks:
We use ping, arping, and traceroute within the virtual router to test
connectivity to other VMs and external networks.
Virtual Router Diagnostics:
we did run "Run Diagnostics" and "Get Diagnostics" features as well but
not
getting any result.
2. Virtual Router Issues:
Force Stop and Restart:
We have tried but no luck.
Destroy and Recreate:
We have tried but no luck.
DHCP Problems:
There is no issue with dhcp.
3. Network Configuration:
Network connection also ok.
Any help would be really appreciated. Thank you!
Regars,
SK
