agents lost connection after cert update

[inderpalr2020]

Hello everyone,

Firstly thanks for the continuous support and a great software!

During our recent web certificate change we noticed that most of our agents have lost there connection after the web cert change. We did not change the agent certs they were as it is. But the web cert was changed with a new cert.

If we now change back to the old cert we see the agents are able to connect without issues.

Some observations:

1. Few of the agents are still online, even after new web cert and new agent cert(as a check we backed up old agent cert and created new these agents were not affected) (This looks like to me the agent are not authenticating with these agent certs)
2. Some agents are online with the new cert change.
3. With only old web cert if changed all agents come up, which they dont with the new cert.

Troubleshooting:
{
"settings": {
"Port": 443,
"IgnoreAgentHashCheck": true
}
}

Is there a way we can stop this from happening every year? when we perform cert upgrades.

Thanks!
