Deployed Azure VPN stopped working all of a sudden with no changes made

OS / Environment (where do you run Algo on)

Linux 4.4.0-17134-Microsoft #81-Microsoft Sun May 20 01:14:00 PST 2018 x86_64 x86_64 x86_64 GNU/Linux

Cloud Provider (where do you deploy Algo to)

Azure

Summary of the problem

I have been running a deployed Algo on Azure for a month or two with no problems at all. A few days ago (6/18), it all of a sudden stopped working with no changes made. Now my windows 10 device and iPhone cannot connect to the internet if it's connected to the VPN. I initially tried deleting everything from Azure and re-deploy. The problem persisted. I am now confused as to where the problem really is. Any help is appreciated. Thanks in advance!

Steps to reproduce the behavior

Changed config settings below:

If True re-init all existing certificates. (True or False)

easyrsa_reinit_existent: False

vpn_network: 10.19.48.0/24 vpn_network_ipv6: 'fd9d:bc11:4020::/48' wireguard_enabled: true wireguard_port: 51820

You might want to deploy a new server. We loosed some of the CPU accounting (cgroups) on the various services running. Algo typically fails when it goes over one of those limits and then cgroups halts a process. Login to the server and check dmesg for any such notices to verify.

Redeploying was actually the first thing I tried, as mentioned above. But the problem continued after. Attached below are the logs I got from the newly deployed server. I didn't see any messages for cgroups. It would be great if you can take a look and point me in the right direction. Thanks a lot!
